Question

Using tables, Excel formulas, etc.

Part I - Do Students Really Cheat? (30%) In a recent poll 400 students were asked about their experiences with witnessing academic dishonesty among their classmates. Suppose 172 students admitted to witnessing academic dishonesty, 205 stated they did not and 23 had no opinion. Use the sign test and a significance of 0.05 to determine whether there is a difference between the number of students that have witnessed academic dishonesty compared to those that have not.

Part II – Is There Really a Difference in Studying vs. “Obtaining Answers” (30%) Salaries were collected by recent graduates that were placed in groups that either admitted to dishonesty during college or they were honest the entire degree. We wish to test if after graduation their salaries are the same or if there is a difference in their salaries? Use a level of significance of 0.10. Be sure to clearly state what you are testing as well as interpret your final results. The data is as follows:

Honest	Dishonest
43500	13500
32700	32500
36800	33000
53000	12900
47690	33500
32255	32400
81000	18850
35000	21500
42555	39500
55000	22600
42000	53000
32500	41900
41400	32800
43000	41000
