Question
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 random sample of 30
managers in the state are listed. At a = 0.01, is there enough evidence to support the claim? Use technology.
