Required information A tire company claims that the lifetimes of its tires average 4.98E4 miles. The standard deviation of tire lifetimes is known to be 4,750 miles. You sample 75.0 tires and will test the hypothesis that the mean tire lifetime is at least 4.98E4 miles against the alternative that it is less. Assume, in fact, that the true mean lifetime is 4.93E4 miles. If the test is made at the 5% level, what is the power? (Round the final answer to four decimal places.)
