6 Solve the problem. An industrial supplier has shipped a truckload of teflon lubricant cartridges to an 9 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 12 carefully weighed. Summary statistics for the sample are: x = 1011 ounces, s = 30 ounce. To determine whether the supplier's claim is true, consider the test, Ho: H = 10 vs. Ha: u> 10, where u is the true mean weight of the cartridges. Find the rejection region 15 for the test using alpha = 0.05. Ot> 1.833, where t depends on 9 df Oz> 2.33 Ot> 2.821, where t depends on 9 df ( 12 > 2.58 Question 7 (1 point) Solve the
