At a "Healthy Employees for BC" seminar, the chief executive officer, Ms. Bewie-Bewie Wych learned that healthy employees had lower stress ratings, less absenteeism and higher productivity. She also learned that if she could lower absenteeism, she would get a big bonus. Before mandating such a program for her 400 employees, she asked Dr. Strapp to test this health program for 6 months with 20 of her managers randomly sampled with the restriction that each condition (exercise, no exercise/control) was gender- balanced. Eighteen (nr = 18) managers completed the study. The other two went on extended sick leave. At the conclusion of the health program, a standardized work-related scale, the TTB-LTB inventory (Tote-That-Barge-Lift-That Bale) was used to measure productivity. Scores on this scale range from 0 to 12, with low scores associated with low levels of productivity. 7 8 9 10 8 9 11 11 6 9 x b. Define all the distributions associated with this research design.
