A politician claims that the mean salary for managers in his state is more than the national mean, $80,000. Assume the the population is normally distributed and the population standard deviation is $9200. The salaries (in dollars) for a random sample of 30 managers in the state are listed. At a=0.03, is there enough evidence to support the claim?
