During the global recession of 2008 and 2009, there were many accusations of unethical behavior by Wall Street executives, financial managers, and other corporate officers. An article appeared at that time, suggesting that part of the reason for such unethical business behavior may stem from the fact that cheating has become more prevalent among business students (Chronicle of Higher Education, February 10, 2009). The article reported that 56% of business students admitted to cheating at some time during their academic career as compared to 47% of nonbusiness students. The dean of the College of Business at Bayview and many professors have assumptions about their students regarding cheating behavior. Some think it is a major problem; others do not. To resolve some of these issues, you decide to use a class capstone project to conduct a study about cheating behavior at Bayview. As part of your study, you decide to administer an anonymous exit survey to 90 business students from this year's graduating class. Responses to the following questions will be used to obtain data about three types of cheating. Required:
a. During your time at Bayview, did you ever present work copied from the Internet as your own?
b. During your time at Bayview, did you ever copy answers from another student's exam?
c. During your time at Bayview, did you ever collaborate with other students on projects that were supposed to be completed individually?
d. Any student who answers Yes to one or more of these questions will be considered to have been involved in some type of cheating. After calculating the proportion of Bayview students who have cheated to be = 0.4111, you would like to place the sampling distribution of and its 95% confidence interval in your research report. Construct a 95% confidence interval.
