To the dean of Bayview University, Peter Dalley:

A study was assessed on the current ethical behavior of business students at Bayview. A sample of 90 business students from this year’s graduating class was anonymously given a survey with the following questions: During your time at Bayview, did you ever present work copied off the Internet as your own?

Yes _________ No _________

During your time at Bayview, did you ever copy answers off another student’s exam?
Yes _________ No _________

During your time at Bayview, did you ever collaborate with other students on projects that were supposed to be completed individually?
Yes _________ No _________

Males: 0.56 – 0.58
Females: 0.46 – 0.51
This concludes that within 52%-54% of all the business students are cheaters and within that interval, 56%-58% are males and 46%-51% are females. It shows that male business students are more likely to cheat than female business students.

Ha: p ≥ 0.56
With level of significance as 0.05, Z-value is -0.58
Z-0.58 = 0.28 < 0.56, therefore we do not reject the null hypothesis. This means, there are less business student cheaters in Bayview University compared to other institutions.

As for the nonbusiness student cheaters, our hypothesis test is as...
