Statistics

A manufacturer will not accept a shipment of parts from a vendor if there is reason to believe that the mean diameter of the components is not 100 millimeters. A random sample of 25 parts selected from a large shipment yields a mean of 96 millimeters and a standard deviation of 10 millimeters. Should the shipment be accepted? Use a .02 level of significance and the confidence interval approach to justify your answer.
