The manager of Tammy Corporation wants to determine whether or not the type of work schedule for her employees has any effect on their productivity. She has selected 15 production employees at random and then randomly assigned five employees to each of the three proposed work schedules. The following table shows the units of production (per week) under each of the work schedules.
Work Schedule (Treatments)
Schedule 1 Schedule 2 Schedule 3
50 60 70
60 65 75
70 66 55
40 54 40
45 57 55
At a 0.05 level of significance, determine if there is a significant difference in the mean weekly units of production for the three types of work schedules (perform all six steps of hypothesis testing and show the ANOVA table).
