16. Aretail computer store is considere offering a two-year service warranty, instead of its current one-year plan. In order to do they must determine the average service costs for their systems in the second year of operation. A committee of technicians, sales, and management staff believe that the average repair cost in the second year should be approximately $50. Seventy-five customers who purchased machines between two and four years earlier are randomly selected. Tracking the service needs of these customers reveals an average service cost of $38 with a standard deviation of $10.
