A human resources manager is investigating the effectiveness of a new employee orientation program. Three different instructors each train 8 new employees about the company and its policies, and then a test is given to all new personnel. The manager wants to know if differences in test score can be attributed to instructor at an alpha of .05. She observes the following results in SPSS: Mean Standard Deviation
Instructor A 76.75 8.067
Instructor B 84.13 8.871
Instructor C 90.75 6.964
Total 83.88 9.625

Within Groups 1345.875 21 64.089
Total 2130.625 23

The null hypothesis that all three group means are equal is rejected. She wants to do a Tukey HSD to determine how the means differ from one another, but her computer freezes. You offer to do it for her by hand.

1. The (closest) tabled value for the studentized range statistic (q) is (to 2 decimals).
2. The appropriate value for the MSW (aka MSE) is (to 3 decimals).
3. The appropriate value for n is .
4. The HSD value is (to 2 decimals).
