A study was found that the average stopping distance of a university bus traveling 50 miles per hour was 264 feet (Snapshot, USA TODAY, March 12, 1992). A group of automotive engineers decided to conduct a study of its university buses and found that for 25 buses, the average stopping distance of buses traveling 50 miles per hour was 262.3 feet. The standard deviation of the all buses at university was 3 feet. Test the claim that the average stopping distance of the company’s buses is actually less than 264 feet. Should the null hypothesis be rejected at α=0.01
