Global recession of 2008 and 2009
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. At that time, an article appeared 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. The article reported that 86% of business students admitted to cheating at some time
during their academic career as compared to 77% of non-business students.
Cheating has been a concern of the dean of the College of Business at Rocky University for several years. Some
faculty members in the college believe that cheating is more widespread at Rocky than at other universities, while
other faculty members think that cheating is not a major problem at the college. To resolve some of these issues, the
clean commissioned a study to assess the current ethical behavior of business students at Rocky. As part of this
study, an anonymous exit survey was administered to a sample of 90 business students from this year’s graduating
class. Responses to the following questions were used to obtain data regarding three types of cheating.
0 During your time at Rocky, did you ever present work copied off the internet as your own?
Yes
No
0 During your time at Rocky, did you ever copy answers off another student’s exam?
Yes
No
0 During your time at Rocky, did you ever collaborate with other students on projects that were
supposed to be completed individually?
Yes
No
Any student who answered yes to one or more of these questions was considered to have been involved in some
type of cheating. The complete data set is in the file named Rocky, linked at the bottom of the page.
Managerial Report
Prepare a report (see below) for the dean of the college that summarizes your assessment of the nature of cheating
by business students at Rocky University. Be sure to include the following seven (7) items in your report.
1. To summarize the data, compute the proportion of all students, the proportion of all male students,
and the proportion of all female students who
a. presented work copied off the internet as their own
b. copied answers off another student’s exam
c. collaborated with other students on projects that were supposed to be completed
individually.
Then comment on your findings.
2. Develop 95% confidence intervals for the proportion of all students, the proportion of all male
students, and the proportion of all female students who were involved in some type of cheating.
3. Develop 95% confidence intervals for the proportion of all students, the proportion of all male
students, and the proportion of all female students who were involved in copying off the internet.
4. Develop 95% confidence intervals for the proportion of all students, the proportion of all male
students, and the proportion of all female students who were involved in copying off another's
exam.
5. Develop 95% confidence intervals for the proportion of all students, the proportion of all male
students, and the proportion of all female students who were involved in collaborating on an
individual project.
6. Conduct a hypothesis test (using either the p-value approach or the critical value approach) to
determine if the proportion of all business students at Rocky University who were not involved in
