In April 1994, during a spring of unusually good hitting in professional baseball, a columnist for the Toronto Star hinted at a "conspiracy" by managers in which they "juiced" the baseballs to increase excitement in the game. Suppose that tests of the old balls showed that when dropped 24 ft onto a concrete surface, they bounced an average of 92.14 in. In a test of a sample of 40 new balls, the bounce heights had a mean of 92.67 in. and a standard deviation of 1.79 in. Use a 0.05 significance level to test the claim that the new balls have bounce heights different from 92.14 in. Are these balls "juiced"?
