A manufacturer of electronics will not accept a shipment of parts from a vendor if there is reason to believe that the mean resistance of the components is not 100 ohms. A random sample of 30parts selected from a large shipment yields a mean of 96 ohms and a standard deviation of 10 ohms. Should the shipment be accepted? Use a .02 level of significance and the confidence interval approachto justify your answer.
