Essential Statistics for Public Managers and Policy Analysts / Edition 3 by Evan M Berman, Xiaohu Wang 1-Use the public perception dataset. Is the relationship between watching Orange TV (watch), the county’s cable television station, and trusting the government to do what is right most of the time (trust) statistically significant? Do you consider this a causal relationship or an association? Does the analysis satisfy the assumptions of the Chi-square test? If not, how might you address this problem? 2-Use the public perception dataset. Examine the relationship between residents who trust the county government to do what is right most of the time (trust) and their belief that county government works efficiently (works). What is the practical significant of this relationship? 3-Use the public perception dataset. In Chapter 10 of this workbook, you used Chi-square to examine the relationship between residents who trust the county government to do what is right most of the time (trust) and their belief that county government works efficiently (works). Reexamine this relationship using measures of gamma, Somer’s d, Kendall’s tau-c. What do you conclude? 4-Table W 12.1 is the printout of a t-test (independent samples). The continuous variable is an index variable of environmental concern. The dichotomous variable is a measure of education (college versus no college). Interpret and write up the results. What other information would you like to have about this relationship? 5-Table W 12.2 is the printout of a period-samples t-test. The data are before-and-after measurements of a public safety program. Interpret and write up the results. What other information would you like to have about this relationship? 6-Use the Public Perception dataset. An analyst wants to know whether incomes vary by age group. Treat the income variable as a continuous variable, and treat the age variable as an ordinal variable. Calculate the means for each of these groups, and then use ANOVA to determine whether any of these differences are statistically significant. For which group is the relationship linear?

Question 1 In order to properly manage expenses, the company investigates the amount of money spent by its sales office. The below numbers are related to six randomly selected receipts provided by the staff. \$147 \$124 \$93 \$158 \$164 \$171 a) Calculate ̅ , s2 and s for the expense data. b) Assume that the distribution of expenses is approximately normally distributed. Calculate estimates of tolerance intervals containing 68.26 percent, 95.44 percent, and 99.73 percent of all expenses by the sales office. c) If a member of the sales office submits a receipt with the amount of \$190, should this expense be considered unusually high? Explain your answer. d) Compute and interpret the z-score for each of the six expenses. Question 2 A survey presents the results of a concept study for the taste of new food. Three hundred consumers between 18 and 49 years old were randomly selected. After sampling the new cuisine, each was asked to rate the quality of food. The rating was made on a scale from 1 to 5, with 5 representing “extremely agree with the quality” and with 1 representing “not at all agree with the new food.” The results obtained are given in Table 1. Estimate the probability that a randomly selected 18- to 49-year-old consumer a) Would give the phrase a rating of 4. b) Would give the phrase a rating of 3 or higher. c) Is in the 18–26 age group; the 27–35 age group; the 36–49 age group. d) Is a male who gives the phrase a rating of 5. e) Is a 36- to 49-year-old who gives the phrase a rating of 2. f) Estimate the probability that a randomly selected 18- to 49-year-old consumer is a 27- to 49-year-old who gives the phrase a rating of 3. g) Estimate the probability that a randomly selected 18- to 49-year-old consumer would 1) give the phrase a rating of 2 or 4 given that the consumer is male; 2) give the phrase a rating of 4 or 5 given that the consumer is female. Based on the results of parts 1 and 2, is the appeal of the phrase among males much different from the appeal of the phrase among females? Explain. h) Give the phrase a rating of 4 or 5, 1) given that the consumer is in the 18–26 age group; 2) given that the consumer is in the 27–35 age group; 3) given that the consumer is in the 36–49 age group.

On the other hand, the company reports that the annual returns on tax-free municipal bonds are approximately normally distributed with a mean return of 4.7 percent and a standard deviation of 10.2 percent. Find the probability that a randomly selected a) Common stock will give a positive yearly return. b) Tax-free municipal bond will give a positive yearly return. c) Common stock will give more than a 13 percent return. d) Tax-free municipal bond will give more than a 11.5 percent return. e) Common stock will give a loss of at least 7 percent. f) Tax-free municipal bond will give a loss of at least 10 percent. Question 4 Based on a sample of 176 workers, it is estimated that the mean amount of paid time lost during a three-month period was 1.4 days per employee with a standard deviation of 1.3 days. It is also estimated that the mean amount of unpaid time lost during a three-month period was 1.0 day per employee with a standard deviation of 1.8 days. We randomly select a sample of 100 workers. a) What is the probability that the average amount of paid time lost during a three-month period for the 100 blue-collar workers will exceed 1.5 days? Assume σ equals 1.3 days. b) What is the probability that the average amount of unpaid time lost during a three-month period for the 100 workers will exceed 1.5 days? Assume σ equals 1.8 days. c) A sample of 100 workers is randomly selected. Suppose the sample mean amount of unpaid time lost during a three-month period actually exceeds 1.5 days. Would it be reasonable to conclude that the mean amount of unpaid time lost has increased above the previously estimated 1.0 day? Explain. Assume σ still equals 1.8 days.

1 Hankerson Project Three: Culture and the African American Experience The Media Analysis This project will help you: ?develop your analytical skills. ?expand your understanding of media and how it operates. Background: For this project, we will examine select media representations of the African American culture. These media representations will further our understanding of how media portrayals–specifically African American media portrayals–operate. Ultimately, we will use this knowledge to engage with the overall task for this project which asks us to write a media analysis about a cultural media portrayal of interest. Task: As a frame for this project, we will draw from Afrobella’s DzAn Open Letter to Hip Hopdz which explores Afrobella’s perceptions of the state of hip hop. Your task for this project will be to compose a media analysis about Afrobella’s DzAn Open Letter to Hip Hop.dz Alternatively, you may wish to write a media analysis about another cultural media portrayal. In either case, you are asked to perform a thoughtful, close analysis of the media source. In specific, in either case, you are asked to: 1) interpret the underlying messages or implications that exist within themedia source, and 2) interpret the effectiveness of the media source.

Consciously and sub-consciously we have “boxed” leadership in the same way. Looking back we interpret events and interactions, sort out the relevant and important, and apply meaning to the events. This assignment we will use Steve Jobs as our point of focus and our source for leadership events– our retrospective examination of his life as a leader. Assess Jobs as a leader from each perspective: 1. Traits (why traits failed) 2. Style (why style was underutilized) 3. Skills (skills that should have been used) Explain how Jobs’ leadership is explained through the lens of each: 1. Path-Goal 2. LMX 3. Transactional 4. Transformational 5. Charismatic 6. Authentic Non-traditional: 1. Follower (was Jobs a follower, how were followers a part of Jobs’ leadership?) 2. Conclusion (final heading – best represents Jobs and why others were ruled out) • APA format (margins, font, spacing) • APA in-text citations when needed • APA reference page • Proofread for grammar and content • Ensure that all headings and questions are addressed See agenda for headings Remember, this is a detailed analysis. Each of the above (a-j) should be a heading and explain how Jobs, as a leader, represents (or does not represent) the corresponding school of thought. Provide supplemental sources to give your position more credibility, but keep in mind that this is not a biography of Jobs (there are many recent biographies that do not qualify as acceptable sources for this assignment). Finally, which leadership perspective best identifies Steve Jobs as a leader? Explain why, and explain why other options were ruled out (k).
