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 = 10 cartridges are randomly selected from the shipment and carefully weighed. Summary statistics for the sample are: overbar(x) = 10.11 ounces, s = .30 ounce. To determine whether the supplier's claim is true, consider the test, H 0: = 10 vs. (H) with subscript (a): > 10, where is the true mean weight of the cartridges. Find the value and correct use of the critical value for the test using = .01. | z| > 2.58 z > 2.33 t > 2.821, where t depends on 9 df t > 3.25, where t depends on 9 df
