Good Versus Evil Essay Example for Free

Good Versus Evil Essay Good versus Evil At first, it appears that the definitions of good and evil are straightforward. According to the New Oxford American Dictionary, good is defined as â€Å"that which is morally right; righteousness†; evil is defined as â€Å"profoundly immoral and malevolent. † For centuries there has been an argument among many philosophers on the belief of â€Å"good versus evil† and whether it really exists. Some argue that human beings are the perpetrators of evil. Others argue that the world is not a bad place and that evil and suffering is, in fact, necessary. Throughout the novel, Frankenstein by Mary Shelley, there is a clear struggle involving good and evil. The reader is introduced to the protagonist and narrator, Victor Frankenstein, at the beginning of the novel. Victor, a family oriented man, becomes very interested in the modern science world and later on believes that he has discovered the â€Å"secret of life. † With this discovery he goes on to create a monster, who remains without a name throughout the whole novel. At first glance it appears that the monster did everything in his power to prevent Victor from having the happy life that he longed for. Mary Shelley purposely chose Victor Frankenstein to be the narrator of this story. Readers only get the story from his point of view. Frankenstein plays on the emotions of the readers, therefore anything he is feeling, readers feel the same way. He is seen as this helpless man who has been through so much in such a short life, and all because he was being terrorized by this heinous creature. â€Å"I entered the room where the corpse lay, and was led up to the coffin The trial, the presence of the magistrate and witnesses, passed like a dream from my memory, when I saw the lifeless form of Henry Clerval stretched before me. I gasped for breath; and, throwing myself on the body I exclaimed, ‘Have my murderous machinations deprived you also, my dearest Henry, of life? Two I have already destroyed; other victims await their destiny: but you, Clerval, my friend, my benefactor’† (122). However, readers do get a glimpse in to how the monster feels and the struggles that he comes across. â€Å" She continued her course along the precipitous sides of the river, when suddenly her foot slipped; and she fell into the rapid stream. I rushed from my hiding place, and, with extreme labour from the force of the current, saved her, and dragged her to shore I was suddenly interrupted by the approach of a rustic On seeing me, he darted towards me, and, tearing the girl from my arms, hastened towards the deeper parts of the wood he aimed a gun, which he carried, at my body, and fired. I sunk to the ground, and my injurer, with increased swiftness, escaped into the wood† (95). Mary Shelley’s anecdote of a struggle between good versus evil makes the reader constantly redefine who is truly the good one, and who is evil. At the end of the novel, the reader discovers that it is really Victor Frankenstein that is the evil one. He manipulated the readers thoughts and feelings by leading them to believe that he was the good one, that he was being tormented by this evil beast. In reality, this is how the story really goes: Frankenstein was the creator of this â€Å"beast. † Frankenstein abandoned the beast and treated it as if it were too wretched to be loved. Frankenstein, knowing how the beast felt and what he was capable of, continued to ignore the monster’s requests for a companion. Frankenstein knew that the beast would take away all of his loved ones until he got what he wanted. Victor manipulated this monster in to doing his dirty work for him. Mary Shelley displays this battle between good and evil very well. Candide, written by Voltaire, is a satire which pokes fun at a number of Enlightenment philosophies. The protagonist, Candide, is a good-hearted but naive young man. His mentor, Pangloss, is described as a teacher of â€Å"metaphysico-theologo-cosmolonigology† who believes that this is â€Å"the best of all possible worlds. † This belief, which is argued by Leibniz, is the main reason why Voltaire is satirizing his play. Pangloss is an optimist, and believes that no matter what happens, this is the greatest life anyone can live because the good will always be the case. Voltaire mocks the idea that good prevails over evil because he believes that human beings perpetrate evil. He believes that evil does, in fact, exist and ignoring that existence is wrong and dangerous. Other philosophers such as Leibniz believe that the existence of any evil in the world would have to mean that God is either not good or not omnipotent, and that idea could not possibly be true. With this reasoning, philosophers such as Leibniz believe that since God is indeed perfect, then the world that he has created can be viewed as no less than perfect as well. All the â€Å"evil† or â€Å"bad† that people claim exists in the world is only because they do not understand what God’s ultimate plan is. Voltaire strongly disagrees with this idea, as it is evident in his novel. He does not accept the idea that a perfect God exists, maybe a God does not even exist. To prove his point, Voltaire uses a great deal of exaggeration; the biggest optimists in the world, Candide and Pangloss, go through a series of hardships and horrors. These woes do not serve any apparent purpose but to attack this belief that this is â€Å"the best of all possible worlds. † A perfect example is when Pangloss tells Candide that he is dying because of syphilis. In chapter four, Candide cries, â€Å"O sage Pangloss what a strange genealogy is this! Is not the devil the root of it? † Pangloss simply replies, â€Å"Not at all, it was a thing unavoidable, a necessary ingredient in the best of worlds; for if Columbus had not caught in an island in America this disease, which contaminates the source of generation, and frequently impedes propagation itself, and is evidently opposed to the great end of nature, we should have neither chocolate nor cochineal. † This part of the novel makes the reader laugh because chocolate is not the result of syphilis; they are in, no way, related. Voltaire then adds more intelligent and rational characters into the story, such as the old woman, who have more pessimistic views about how the world works. By the end of the novel, Pangloss finally admits that maybe this is not â€Å"the best of all possible worlds. † Shelley, Voltaire, and Leibniz all touched on the subject of good versus evil. Voltaire and Leibniz had opposing views on how the world really works. Maybe there is a bigger plan, but evil does exist and evil is created by all of us. Shelley definitely showed how humans can truly be evil. No matter what, there will always be a battle between good versus evil.

Ethics in Machiavellis The Prince Essay -- Machiavelli The Prince

Ethics in Machiavelli's The Prince Niccolo Machiavelli (1469-1527) was an Italian statesman and political philosopher. He was employed on diplomatic missions as defence secretary of the Florentine republic, and was tortured when the Medici returned to power in 1512. When he retired from public life he wrote his most famous work, The Prince (1532), which describes the means by which a leader may gain and maintain power. The Prince has had a long and chequered history and the number of controversies that it has generated is indeed surprising. Almost every ideology has tried to appropriate it for itself - as a result everyone from Clement VII to Mussolini has laid claim to it. Yet there were times when it was terribly unpopular. Its author was seen to be in league with the devil and the connection between 'Old Nick' and Niccolo Machiavelli was not seen as merely nominal. The Elizabethans conjured up the image of the 'murdering Machiavel' [1] and both the Protestants and the later Catholics held his book responsible for evil things. Any appraisal of the book therefore involved some ethical queasiness. Modern scholarship may have removed the stigma of devilry from Machiavelli, but it still seems uneasy as to his ethical position. Croce [2] and some of his admirers like Sheldon Wolin [3] and Federic Chabod [4] have pointed out the existence of an ethics-politics dichotomy in Machiavelli. Isaiah Berlin [5] postulates a system of morality outside the Christian ethical schema. Ernst Cassirer [6] calls him a cold technical mind implying that his attitude to politics would not necessarily involve ethics. And Macaulay [7] sees him as a man of his time going by the actual ethical positions of Quattrocento Italy. In the face of s... ...erlin, Isaiah. The Question of Machiavelli.

My Grandmother Essay

Everybody has one important person in their lives. For me, the most influential person in my life is my grandmother. She is a traditional Chinese woman. When I was a child, my grandmother had been blind since I was not born, but she is nimbler than most people. My grandmother took care of me when I was a baby. Although my grandmother is dead, I still miss her, because she taught more experiences to me and these have changed many things in my mind. When I was a little girl, my parents went to another place for their work. Therefore, my grandmother took care of me at home. However, I thought that my parents did not love me because they were not like other parents who stayed at home. I felt my life was lost color. I always felt so bored and unhappy, because other children did not want to play with me, and I lost my parents’ love. Over some time, my character became lonely and shy. I thought that I would not have anymore changes in my life. However, my grandmother used something to change my thinking. One day, I was very unhappy and worrying about coming back home. When my grandmother knew that I was back, she cooked some dessert for me. But I did not want to eat anything. My grandmother was very worried about me and she asked me what happened. I told her that my teacher needed me to choose one story for speech in the classroom at next week. I was worrying about it because I was a shy girl and I did not believe that I could do it. After my grandmother understood the reasons, she laughed at me. I felt so uncomfortable. Therefore, I made a decision for this speech. But I always felt very angry about my grandmother’s behavior, and I did not want to talk with her. For a while, my grandmother did not laugh again. She said that this was a good chance for me and I must try to do it. I always did not want to talk about anything with her. Nevertheless, my grandmother still told one story to me. When she finished this story, she taught me who had the confidences and bravery to solve this problem. After this day, my grandmother requested me, who told one story to her in every night. Because of my grandmother’s training, I improved my speech and I became brave. So I was successful to tell this story to my classmates in the classroom. In this matter, I know that nothing is impossible. If I want to do anything, then I must be brave to do it. Because of my grandmother is teaching me, I changed shyness in my life and I was very happy for this change. I did not feel lonely again, because many children liked the story I told them, and then they wanted to play with me. My grandmother taught more experiences to me. Furthermore, she was a good grandmother because she knew that how to take care of me. For example, I felt very bad one morning. My grandmother touched my face, and then she said that I was sick and I needed to rest. I heard my grandmother because although my grandmother did not see anything, she knew more things. At the night, I still felt very bad and I was afraid about my disease. However, my grandmother comforted me. She took care of me. The next morning, I felt so good and strong. When I looked at my grandmother’s face, I was crying because I felt she was so tired to take care of me. However, my grandmother was so happy to comfort me and she said that she was fine. At now, I think that my grandmother is a great woman. Because of my grandmother is care. I know that many people need our help when they have trouble. I learned how to help those people from my grandmother. On the cold day, my friend and I came back home from school, we were very happy to talk with each other. Suddenly, my friend fell on the road and got hurt. She was crying. I did not know how to comfort her because her knee was bleeding. I looked for other people, but nobody came. I was very anxious and worried about her. At this time, I wanted to cry, but I knew that I could not cry because if I was crying, then my friend would be worrying about more things. Therefore, I tried to think of some ideas to help my friend. All at once, I remembered that my grandmother taught me how to cure her wound. I went to comfort my friend. At the same time, I immediately looked for one of medicinal herbs to cure her wound. In the end, I found the medicinal herbs to cure her wound, and then she did not cry. I was took my friend to go back her home. My friend and her mother said thanks for my help. When I came back home, I told to my grandmother about this. She was so happy to praise me. At this moment, although I felt very tired, I was glad to hear about it. After this time, I understood why my grandmother taught me to help other people. Therefore, I had been deciding to help much more people. My grandmother has many roles in my life. Sometimes my grandmother is like a best friend, she would share most interesting stories to me. Sometimes my grandmother is like a rigorous teacher. She passed much knowledge from her experiences to me, and she would request me who must change bad behavior. Sometimes my grandmother is like a chef. She could cook the most delicious food for me. According to my grandmother, I realize that my parents work in another place for our lives, and they love me very much. Therefore, I think that my grandmother is very important in my life. Furthermore, I believe that I do not forget her teaching forever, and I feel very happy to live with my grandmother

Advantages of mass media Essay

Mass media refers collectively to all the media technologies that are intended to reach a large audience via mass communication. There are various forms of mass media such as radio, television, movies, magazines, newspapers and the World Wide Web. Mass Media enjoys a very prominent role in our lives and thus, it is believed to influence our society. There are positive and negative effects of mass media on our society. This essay will discuss the advantages and disadvantages of mass media and state if the advantage or disadvantage outweighs the other. The first advantage of mass media is that it promotes democracy. Talk shows and debates that are conducted on the radio gives people chance to voice out their opinions and express their views of ideas about a particular issue. This use of radios makes it a â€Å"free market place of ideas† where people get informed of the multiple ideas that can be learned about a topic. Also this advantage of mass media allows arguments to be otherwise of the discussed perspective of an issue to voice out the contrasting feelings of people without the fear of being pointed to by the authorities if opinions are subjective. Moreover, free press keeps the government under constant monitoring and checks. It helps the general public to question issues that highlight policy failures, maladministration, scandals and corruptions and this makes mass media the voice of the disadvantaged. A long tradition of liberal theorists claimed that a free and independent press within a nation can play a vital rol e in the process of democratization by contributing towards the right of expression, thought and conscience, strengthening the responsiveness of government to all citizens and providing a pluralist platform of political expression for a multiplicity of groups. Thus, radio being an example shows the positive relationship between mass media and democracy. Read more: Advantages and Disadvantages of Mass Media Furthermore, mass media promotes health education. A way in which societies can grow is through good health and studies assert that media has a responsibility to help people live a healthy life. In Uganda, for instance, FM radios conducted programs where medical doctors were invited to a program  to talk about general or specific diseases, their causes, symptoms and how to avoid these diseases or where to seek treatment. Namely, Radio-Wa conducted a program, Meet The Doctor, on which a doctor from Lira Hospital appeared every Sunday from 5.00 pm and discussed popular medical issues, such as, current health problems of reproductive health diseases and sexually transmitted diseases, for about an hour. Through another research, it was found that radio listeners took active part in these kinds of programs and they were able to learn about many diseases that they were suffering from unknowingly. Majority of the listeners were able to cure their diseases. Thus, mass media assists people to keep informed about medical and health issues. In addition, mass media plays a very vital role in accounting for agricultural trade. Radio, one of the fastest forms of mass communication, has been used in communicating farm information to farmers for a long time and since then radio has been used as a mass communication for agricultural development. Rural communities need information on supply of input, early warning systems for drought and diseases, new technologies and market price and information about their competitors. Such information through mass media contributes to the expansion of agriculture. After looking at factor such as the continuing expansion of market oriented agriculture and the increasing complexity of input requirements, studies suggested that there is a need for a continues education of farmers and extensions and thus concluded that radios and television would be a good way to disseminate information to them. Another research showed that 58 % of the respondents regarded radio as the most effective channel fo r dissemination of agricultural information. Thus information about trade from mass media would likely result in benefiting the whole economy along side with the entrepreneurs of such trading businesses. On the other hand, mass media broadcasts negative information to teen agers, especially females, about sex related topics. Movies and televisions are two examples of sources from where teens absorb information about sex and sexuality. These sources give unrealistic images of the portrayed topics. A study shows that an average teen ager is exposed to approximately 14000  references of sex of which less than a percent of the references imply information about abstinence, birth control, pregnancy risks, and sexually transmitted diseases. In addition, mass media uses females as sex objects. In most music videos, females are approximately half the time dressed in clothes that expose their breast and rear ends. The sexual attractiveness of music videos and similar imaged mass media encourages teens as well as adults to expose themselves in public, inviting them to become victims of unethical crimes, such as, rape. Moreover, mass media depicts non realistic body images. This disadvantage of mass media depiction leads majority of the viewers toward unhealthy eating habits. Young people are getting encouraged by skinny models on the TV to lose weight and get their body into a sexy image. Researchers are claiming that males are becoming more insecure about their physical appearance as advertisements are painting images of idealistic well built muscular body. A study found that girls as young as eight years old are weight conscious and are on strict diets. Many other females smoke to keep their weight off and through research, it is found out that there is approximately 400% increase in eating disorder since 1970.Like females, boys also tend to smoking to lose weight. A survey by Teens Magazine reported that 27% of the females felt that media pressured them to have a perfect body and 69% of girls state that magazine models influence their thought of being slim and slender. Media’s role in po rtraying unrealistic images of body figures can lead to serious health problems and deadly diseases as attendants to media are evidently being influenced by the false images. In addition, mass media promotes gender and racial unfairness in a society. Women, through media, are treated in disrespectful manners and are referred by the use of unethical words, such as, â€Å"a whore† or â€Å"a slut†. These kinds of words can be heard over the radio and seen in movies and televisions, for instance, the use of the word â€Å"bitch† in reference to women can be seen in wrestling programs exposed young children to witness it without supervision. Advertisements also promote gender biasness as they mostly include women in a sexual way to sell product. A study on advertisements showed that males are only seen in 25% of the advertisements on scantily wears, for example,  underwear advertisements. The same study quoted that roughly 62% of white women were noticed in the same kind of advisements and the figure for black women was 53% only. Also, black women were mostly shown in animal prints and in predatory poses to highlight their powerlessness . Thus, mass media is openly bias towards the sexes and races of different kinds of people. Besides its other disadvantages, mass media is known to lead young children to aggressive violence. Media violence is harmful to kids because of their inability to differentiate between reality and fantasy. A study showed that by the age of 18, an average teen ager has viewed approximately 200000 acts of violence on television, ignoring other sources of mass media. These violent clips increase aggressiveness and anti social behavior in children and it also increases their thirst for violence in the real life. Hence children are traumatized by the violent images and as a result they end up committing violent acts themselves. In conclusion, it is clearly argued that mass media has both advantages and disadvantages. The issues that are discussed in this essay evidently suggest that the disadvantage of mass media outweighs the advantages yet some of the disadvantages of mass media can be avoided.

image analysis on photographers Essays

image analysis on photographers Essays image analysis on photographers Essay image analysis on photographers Essay Image Analysis William Klein (1955) ,Broadway and 103rd Street, New York Available at: amicortina. com/fotpuntvistaingles/kleine. htm [Accessed 5 November 2012] DescriptionWilliam Kleins collection NEW YORK marks an important time in the history of photography during the latter half of the 20th century. The photograph Broadway and 103rd Street, New York (1955) captures New York street life during the time period, with the morbid image of a youth walking the streets of the city while playing with a revolver. The boys face is full of anger and rage, which therefore seems to be a reflection of the environment he is in. He points the revolver at the photographer but that doesnt bother the photographer and he still shoots the picture without 1 second thought. He used a wide-angle lense, which provided him with enough depth to him, probably his younger brother looks up at him with respect and admiration. The medium of the photograph is a black and white picture, which looks like it is cropped out of a larger picture. Born in 1928, William Klein belonged to a very poor Jewish Family who had immigrated from their country and started to live in New York, in an Irish neighborhood leading to him feeling estranged at school and on the streets. He was a bright pupil who had a liking at a very young age of the arts and humanities. He studied Sociology and later was also part of the US army for 2 years. In 1948, Klein went to study briefly in Paris and eventually began living there. When he returned to New York in 1954 for a visit, he decided that he wanted to photograph New York in a new way and wanted to keep a photographic diary. It was during this time that some of Kleins most famous work was created. The picture shown above is also from that time. New York in the 1950s suffered from a big racial divide. It was the era Just before the civil rights movement and it was a time of turmoil for people in the city. There was a downturn in the industry and commerce sectors, which lead to fewer opportunities for good Jobs in the future. Youngsters became cynical and were aware of the cultural, ethnic, class barriers. Therefore in Kleins photographs we see how he represents a ore explicit, vulgar perspective of the city. People struggles through all odds and the dismal mood of the city lowered the emotional prospect of the future. l was a make believe ethnographer- treating New Yorkers like an explorer would treat Zulus- searching for the rawest snapshot, the zero degree of photography. (William Klein, 1956, p. 120) Klein is known for his extensive use of wide-angle lense. In the early 50s Klein was introduced into the photography world, with a collection of books about cosmopolitan cities such as New York, Moscow, Rome and Tokyo. His black-and-white hotography catches the onlookers attention, as the atmosphere within the work is full of actuality, therefore enabling us to undergo and understand the environment of living in the 50s. His work mostly compromises of raw, gritty, black and white pictures and depicts the vigor and movement of the time with little or no regard for old-style work. As William Klein says in The Guardian: Somebody turned one of the panels when I was shooting on a already abstract shape was a beautiful blur. That blur was a revelation. I thought, heres a way of talking about life. Through photography, you can really talk about what you see around you. Thats what Ive been doing ever since. (Klein, April 2012) When Klein returned to New York he worked for 10 years as a fashion photographer for Vogue. He shot models in the busy streets of New York. It was a first insight into his style of iconoclastic pictures full of blur, and grainy high contrast. He used long-focus and flash and mostly liked to crop and blur his images, to create a feeling that you are a part of the action. Kliens work has a lot of resemblance with another famous hotographer from New York, Diane Arbus. Like Klien she photographs the inhabitants of the city in which she lives and seeks out those who live at the edge of society. Her work emphasizes on the abnormality of a place and is a reflection of ones daily life. The picture below is one of her best-know images shot in 1962, and is of a boy holding a grenade in his hand in Central Park. Similar to Klien she takes pictures of what she sees and doesnt think twice. They both took pictures that were strange and incomprehensibly troubling. Diane Arbus herself never described her work as normal. She would photograph things she did and said because that seemed more interesting to her similar to Klien. They never followed the moral code of photography. William Klein was never interested in photographs 3 that Just tell a story. Like Diane, he also preferred taking pictures that were uncommon and out of the box. Diane Arbus (1962), Boy with Toy Grenade in Central Park Available at: feralpost. comnp=443 [Accessed 10 November 2012] Despite the obvious similarities between the photographers, upon further analysis a few differences begin to emerge. William Klein took pictures of fashion and objects relating to fashion as well as governmental issues that pertained to society. He covered all aspects of his surroundings but on the other hand Diane Arbus only chose to take photographs of one specific topic. There is a definite difference between the mood and tone that the pictures convey by both the photographers. William Kleins pictures seemed more planned and there was a sense of humor behind some of the images he took. They were a lot more comical compared to those of Diane Arbus. SHE-RGILL, ISHE BAFPR NOVEMBER 19, The photograph is a bit shocking and denotes youth and revolt and the lack of color adds depth to the picture. There is a sense of sarcastic rage, which is displayed by the older boy who is holding the revolver. In my opinion, Klein seemed to have a keen interest in the contrast between the boys, both visually and in character. The boy holding the revolver seems particularly aggressive whereas the younger boy, most probably his brother looks nervous and weak. I feel the gritty effect adds to the seriousness of the picture. It seems to me as though they were a mirror image of Kliens personality. As a photographer, Klein seemed to have a reserved and deep attitude towards life but at the same time was in your face, similar to the boy with the gun in the picture. It is believed that Klein himself gave the boy the gun and directed him and told him to do what he wants. Therefore the image, which at first appears to be an impulsive picture of a boy playing, is in actuality a partially directed photograph. As a viewer looking at it now, it totally eliminates the element of intensity from the picture. l WAS AN OUTSIDER, FOLLOWING MY INSTINCTS. (William Klein, 2012)

Practice with p-values Use the density tool to practice finding p-values. I. Set the mean to 35, the standard deviation to 12.5, and the sample size to 100. What is the probability of finding a value: a. less than 33 .055 b. greater than 37.1 .039 c. less than 32.8 or greater than 36.9 .039+.065=.104 II. Change the sample size to 250. Now that the sample size is greater, find the following probabilities and compare them with those found in the first question: a. less than 33 .006 b. greater than 37.1 .004 c. less than 32.8 or greater than 36.9 .003+.008=.011 Larger samples taken from the same population have a much smaller chance to have a mean value far from the population mean. Increasing the sample size by a factor of 2.5 decreased the likelihood of these rare events by a factor of 10. III. Keeping the sample size at 250 and the mean at 35, try changing the standard deviation to 11 (a difference of only 1.5 from the previous standard deviation) and compare these results with the results you obtained in the second question. a. less than 33 .034 b. greater than 37.1 .029 c. less than 32.8 or greater than 36.9 .023+.042=.065 A relatively small, about 10% decrease in the standard deviation had a huge effect increasing (by a factor of 6) the chances for certain sample mean values to come up that are far form the population mean.. IV. Set the mean to 34, the standard deviation to 12.5, and the sample size to 100. Find the following probabilities and compare them with the ones you found in the first question. a. less than 33 .21 b. greater than 37.1 .007 c. less than 32.8 or greater than 36.9 .167+.01=.177 33 is much closer (almost 1.25 closer which would be a full standard deviation closer) to the mean now so chances for a sample mean to be 33 increased dramatically. On the other and 37.1is a full standard deviation further than where it was when the mean was 35. therefore fewer samples show this value. In part c) the lower value got closer the higher value mover further form the mean so it evens out to about the same chance overall as in the corresponding part in I. Write a brief summary of what you observed when certain values were changed. MRA-1. Population Mean Hypotheses Each of the following paragraphs calls for a statistical test about a population mean m. State the null hypothesis H0 and the alternative hypothesis Ha in each case. (a)The diameter of a spindle in a small motor is supposed to be 5 mm. If the spindle is either too small or too large, the motor will not work properly. The manufacturer measures the diameter in a sample of motors to determine whether the mean diameter has moved away from the target. H0: =5 Ha: 5 (b)Census Bureau data show that the mean household income in the area served by a shopping mall is $42,500 per year. A market research firm questions shoppers at the mall. The researchers suspect the mean household income of mall shoppers is higher than that of the general population. H0: =42,500$ Ha: >42,500$ The examinations in a large accounting class are scaled after grading so that the mean score is 50. The professor thinks that one teaching assistant is a poor teacher and suspects that his students have a lower mean score than the class as a whole. The TA's students this semester can be considered a sample from the population of all students in the course, so the professor compares their mean score with 50. H0: =50 Ha: 50 MRA-4. Explaining Ethnocentrism A social psychologist reports that in our sample, "ethnocentrism was significantly higher (p= 0.05) among church attenders than among nonattenders." Explain what this means in language understandable to someone who knows no statistics. Do not use the word "significance" in your answer. Researchers found that the percentage of ethnocentrics was higher among church attenders compared with the same percentage for non-attenders. In fact the evidence for that was so extreme that if there was no difference between the percentage of ethnocentrics between attenders and non-attenders we would see
