7. An employment information service claims the mean annual salary for senior level product engineers is $98,000. The annual salaries (in dollars) for a random sample of 16 senior level product engineers are shown in the table to the right. At a = 0.05, test the claim that the
mean salary is $98,000. Complete parts (a) through (e) below. Assume the population is normally distributed.
