Discuss the Civil Rights Movement in Tennessee from 1935-1968. Focus on how Tennessee would lay the foundation for programs to be carried to states in the lower south. How did the issue of desegregation affect educational facilities, government and politics? How did the movement end, or do you, the student think the movement continues?
Rubric for Case Study Paper
Each student will be required to submit a case study on a violent criminal or criminals. Emphasis should be on the background of the individuals studied and the criminal act(s) or the motivation(s) for the violent acts.
During the course, you will have learned that many theories on criminal behavior overlap, and that it is not uncommon for more than one theory to explain why the criminal act(s) occurred. Your paper should apply these theories of criminal behavior to the subject’s life history. If you desire to do a fictional character or unsolved crime, please clear with the instructor. Do not choose a political or military individual (Hitler, Stalin, Pol Pot, etc.).

1) What is the average length of a company’s policy book? Suppose policy books are randomly sampled from 45 medium-sized companies. The average number of pages in the sample books is 213, and the population standard deviation of 48.

a) Construct a 95% confidence interval for the population mean cost for all fast-food meals in Seattle. Assume the cost of a fast-food meal in Seattle is normally distributed.
b) Using your confidence interval as a guide, draw a conclusion about whether the true (population) cost of a fast food meal has significantly increased from $4.50.
c) Suppose you thought the true cost was $4.75. Does your confidence interval indicate that true (population) cost of a fast food meal has significantly increased?
6) A research firm has been asked to determine the proportion of all restaurants in the state of Ohio that serve alcoholic beverages. The firm wants to be 98% confident of its results but has no idea of what the actual proportion is. The firm would like to report an error of no more than 0.05. How large a sample should it take?
7) True or False: A statistic taken from a sample that is used to estimate a population parameter is called a point estimate.
8) True or False: The width of the confidence interval depends only on the desired level of confidence.
9) True or False: A 95% confidence interval for the population mean implies that the probability that the population mean lies within this interval is 0.95.
10) True or False: When population standard deviation is unknown, sample standard deviation is used and the interval estimation is based on values from the t- rather than the z-distribution.

17) A computer manufacturer estimates that its line of minicomputers has, on average, 8.4 days of downtime per year. To test this claim, a researcher contacts seven companies that own one of these computers and is allowed to access company computer records. It is determined that, for the sample, the average number of downtime days is 5.6, with a sample standard deviation of 1.3 days. Assuming that number of down-time days is normally distributed, test to determine whether these minicomputers actually average 8.4 days of downtime in the entire population. Let α = .01.
18) A study of MBA graduates by Universum for the American Graduate Survey 1999 revealed that MBA graduates have several expectations of prospective employers beyond their base pay. In particular, according to the study 46% expect a performance-related bonus, 46% expect stock options, 42% expect a signing bonus, 28% expect profit sharing, 27% expect extra vacation/personal days, 25% expect tuition reimbursement, 24% expect health benefits, and 19% expect guaranteed annual bonuses. Suppose a study was conducted last year to see whether these expectations have changed. If 125 MBA graduates were randomly selected last year, and if 66 expected stock options, does this result provide enough evidence to declare that a significantly higher proportion of MBAs expect stock options? Let α = .05.
19) Downtime in manufacturing is costly and can result in late deliveries, backlogs, failure to meet orders, and even loss of market share. Suppose a manufacturing plant has been averaging 23 minutes of downtime per day for the past several years, but during the past year, there has been a significant effort by both management and production workers to reduce downtime. In an effort to determine if downtime has been significantly reduced, company productivity researchers have randomly sampled 31 days over the past several months from company records and have recorded the daily downtimes shown below in minutes.

Essay Prompt: Follow this prompt when preparing for your essay.
Prompt: Compare and contrast the three methods of interpreting and evaluating art: art as form, art as context, and art as expression. Write your comparison by evaluating/interpreting any one of the asterisked works of art on the image list using these methods. For a more thorough review of these methods consult the supplementary page. Be sure to address the following: How do these theories evaluate art? What types of claims do these theories make? What are some of the strengths and limitations of the methods you chose?
Image List:
Modes of Analysis:
Formal Analysis: Use the Elements of Art (space, shape, line, light, color, texture or mass) or the Principles of Art (balance, unity/variety, scale/proportion, repetition/rhythm or emphasis/subordination).
Contextual Analysis: You may consider any relevant type of context (physical, cultural, or historical).
!Physical Context [The immediate physical surroundings of an artwork]: Where is the art? Where is the work located? (a museum, gallery, home, town square, palace, church, etc.); What access do you have to the work as a viewer? How is your viewing controlled by the space?; How is the work arranged in the space? What is near the work? Is it categorized, framed, etc.?; What is the function of that place? How does the work function in that space?; How might culture and history play into the physical context? How does physical context play into the history and culture?
!Historical Context [The time and place in which the artwork is created/viewed]: When was the work created? Where was the work created?; What was the social/political climate of this time and place?; How did people live in this context? How did this impact their worldview?; How were artists regarded in this time? What materials were available to them?; How did art function in society? How did this work function in society?; Who is the audience, viewer, and/or patron of this work?; How does this work inform us about this context? How does the context inform us about this work?
!Cultural Context: [the conceptual place an artwork has in a society]: Where was this work created?; What is the social, political, religious, economic, etc. climate of this location?; How does this work function in this culture? How does art function in this culture?; What is the status of artists in this culture?; Who is the patron, viewer, or audience of this work?; How is the work viewed by people now?; What does this work say about this culture? What does this culture say about this work? Expressive Analysis: What is your instinctual reaction to the work of art? What emotions or ideas are present in the work? How are they present? Who was the artist? What were the emotions or ideas of the artist was trying to express? What message was the artist trying to convey? What is the artist’s background? (biography, experiences, family, training, etc.) What are artist’s the attitudes? (religious beliefs, poli1cal leanings, worldview, etc.) What are the artist’s influences? (artists, authors, philosophers, etc.) How is the artist’s background/attitudes/influences present in the work? What is the artist’s context? How does the ar1st fit in that context? What role does the artist play in society? Does he/she have agency?
