Chapin Manufacturing Company operates 24 hours a day, 5 days a week. The workers rotate shifts each week. Management is Interested in whether there is a difference in the number of units produced when the employees work on various shifts. A sample of five workers is selected and their output recorded on each shift. At the 0.01 significance level, can we conclude there is a difference in the mean production rate by shift or by employee?
