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 is 10 cartridges are randomly selected from the shipment and carefully weighed. Summary statistics for the sample are: -20.11.20 To determine whether the supplier's claim is true, we can perform a hypothesis test. In this situation, 1) what population parameter will we be testing? And 2) what is the distribution of the test statistic? (You do not need to perform the test.)
TUULUU EL LLL 1) population proportion (p), standard normal distribution (z) 2) population mean (u), standard normal distribution (z) 3) population mean (u), t-distribution (t) 4) population proportion (p), t-distribution (t) 5) population proportion (p), we have no good test statistic to use in this situation 6) population mean (u), we have no good test statistic to use in this situation
