QUESTION
A company, studying the relation between job satisfaction and length of service of employees, classified employees into three length-of-service
A company, studying the relation between job satisfaction and length of service of employees, classified employees into three length-of-service groups (less than 5 years, 5 to 10 years, more than 10 years). Suppose that µ1 = 65, µ2 = 80, µ3 = 95 and σ = 3, and that ANOVA model (16.2) is applicable.
- What's the distribution of the observations from each treatment group?
- Find E(MST R) and E(MSE) if 25 employees from each group are selected at random for intensive interviewing about job satisfaction. Is E(MST R) substantially larger than E(MSE) ? What is the implication of this ?
