1.Describe in detail the results achieved on the company's test. Ignore other variables for now, just describe the test results. If the company is considering training for the lowest 10% of employees what score would they need to achieve to be exempted from training?

2.Compare the results of the test for both Females and Males. Construct a 95% Confidence Interval for the difference in the test result between Females and Males. What does this imply about relative performance?

3.The company believes that any score above 125 is acceptable. Calculate point estimates for the proportion of Females and the proportion of Males who achieved an acceptable score. Conduct a test to see if there is any difference in the performance of Females and Males according to the proportion of acceptable results.

4.The company is looking at its hiring procedures to make sure they are recruiting acceptably high quality employees. In particular they wish to make sure the average GPA is in the top bracket above 3.0. Conduct a test to see if the company is meeting that standard.

5.If the company is considering using GPA as an appropriate measure for hiring, it would reasonably be expected that GPA would be related to performance on the company test. What can you say about the strenght of the relationship between GPA and test results? How do these results compare to expectations and what does it say about hiring based on GPA?

6.Conduct a test to see if there is any difference on the test performance between employees with and without a higher degree? What does this imply about hiring?
