A politician claims that the mean salary for managers in his state is more than the national mean, $84,000. Assume the the population is normally distributed and the population standard deviation is $7700. The salaries (in dollars) for a rando managers in the state are listed. At a=0.01, is there enough evidence to support the claim? Use technology. 85,753 74,771 80,874 89,459 95,542 87,349 83,781 88,302 93,679 77,478 82,344 90,606 85,484 85,416 78,102 89,432 95,180 73,518 88,662 72 91,146 80,279 71 93,786 91,229 71,775 77,218 96,253 77,709 74 (a) Identify the null hypothesis and alternative hypothesis.
