An industrial supplier has shipped a truckload of teflon lubricant cartridges to an aerospace customer. The customer has been assured that the mean weight of these cartridges is in excess of the 10 ounces printed on each cartridge. To check this claim, a sample of n equals 10 cartridges are randomly selected from the shipment and carefully weighed. Summary statistics for the sample are: x overbar equals 10.11 ounces comma s equals 0.30 ounce. To determine whether the supplier's claim is true, consider the test, Upper H 0: muequals 10 vs. Upper H Subscript a Baseline : mu greater than 10 comma where mu is the true mean weight of the cartridges. Find the rejection region for the test using alpha equals 0.01 .
