A revenue department is under orders to reduce the time small business owners spend filling out pension form ABC-5500. Previously the average time spent on the form was 63 hours. In order to test whether the time to fill out the form has been reduced, a sample of 72 small business owners who annually complete the form was randomly chosen and their completion times recorded. The mean completion time for the sample was 62.7 hours with a standard deviation of 20 hours. State the rejection region for the desired test at a= .01.
