At that time, an article appeared that suggested 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 10, The reported 2009). article that 56 percent of business students admitted tocheating during academic career as at some time compared to 47 percent of nonbusiness students. Cheating has been a ofthe of the College of Business at Bayview Univer- sity for several years. Some faculty members in the college believe that cheating is more widespread at Bayview than at other universities, while other faculty members think that cheating is not a major problem in the college. To resolve some of these issues, the dean commissioned a study to assess the eurrent ethical behavior of business students at Bay- view. 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. During your time at Bayview, did you ever present work copied off the Internet as your own? During your time at Bayview, did you ever copy answers off another student's During your time at Bayview, did you ever collaborate with other students on proj- ects that were supposed to be completed individually? Any student who answered Yes to one or more of these questions was considered to have been involved in some type of cheating. A portion of the data collected follows. The com- plete data set is in the file named Bayview. Copied copied Collaborated Student Internet Yes file WEB Yes YesExplanation / Answer

Hypothesis testing -1
Null hypothesis, ho; the proportion of business students at Bayview University who were involved in some type of cheating is equal to that of business students at other institutions reported by the Chronicle of Higher Education. That is p = 0.56
Alternative hypothesis, h1; the proportion of business students at Bayview University who were involved in some type of cheating is less than that of business students at other institutions reported by the Chronicle of Higher Education, that is p < 0.56

Do not reject the null hypothesis
With z=0.55 and p-value > 0.05 (alpha), I fail to reject the null hypothesis and conclude that the proportion of business students at Bayview University who were involved in some type of cheating is equal to that of business students at other institutions reported by the Chronicle of Higher Education. That is p = 0.56
Hypothesis testing - 2
Null hypothesis, ho; the proportion of non-business students at Bayview University who were involved in some type of cheating is equal to that of business students at other institutions reported by the Chronicle of Higher Education. That is p = 0.47
Alternative hypothesis, h1; the proportion of non-business students at Bayview University who were involved in some type of cheating is less than that of business students at other institutions reported by the Chronicle of Higher Education, that is p < 0.47

Do not reject the null hypothesis
With z=2.29 and p-value > 0.05 (alpha), I fail to reject the null hypothesis and conclude that the proportion of non-business students at Bayview University who were involved in some type of cheating is equal to that of business students at other institutions reported by the Chronicle of Higher Education. That is p = 0.47
Conclusion
Proportion of females who are involved in some type of cheating is more as compared to proportion of males. It is suggested to conduct seminars on importance and benefits of original work. In order to make students involved in this seminar, there should be a slogan competition and prizes should be given for the same. Efforts should be made to involve more females as their proportion in cheating involvement is more as compared to males.
