5. Hiram N. Fryem, owner of the HNF Employment Agency, believes that the agency receives an average of 16 complaints per month from the companies that hire the agency's people. Mollie DeGel, an interviewer is concerned that the true mean is higher than Hiram believes. If Hiram's hypothesis is an understatement, something must be done about the agency's employee screening procedures. A sample of 10 months yields an average of 18 complaints with sample standard deviation of 3 complaints. Construct a test at the 0.01 level of significance.
