Textbook Question

Chapter 13.2, Problem 20E

Routine Maintenance and Defective Parts A manufacturer believes that if routine maintenance (cleaning and oiling of machines) is increased to once a day rather than once a week, the number of defective parts produced by the machines will decrease. Nine machines are randomly selected, and the number of defective parts produced over a 24-hour operating period is counted. Maintenance is then increased to once a day for a week, and the number of defective parts each machine produces is again counted over a 24-hour operating period. The data are shown. At α = 0.01, can the manufacturer conclude that increased maintenance reduces the number of defective parts manufactured by the machines?
