The Occupational Outlook Handbook by the Bureau Of Labor Statistics lists the mean salary for different occupations. A researcher suspects that the mean salary for an entry-level IT support specialist is higher than the figure reported in the Handbook ($60,000). To explore his suspicion, he randomly selected 16 entry-level IT support specialists, and asked their salary. Mean salary was $64,000 for his sample with standard deviation of $4,000. Test the researcher's claim with a significance level of .01.
