The owner of a downtown parking lot suspects that the person he hired to run the lot is stealing some money. The receipts as provided by the employee indicate that the average number of cars parked in the lot is 125 per day and that, on average, each car is parked for 3.5 hours. To determine whether the employee is stealing, the owner watches the lot for 5 days. On those days, the numbers of cars parked are as follows: 120 130 124 127 128 The time spent on the lot for the 629 cars that the owner observed during the 5 days was recorded. Can the owner conclude at the 1% level of significance that the employee is stealing? (Hint: Since there are two ways to steal, two tests should be performed.)
