Problem 1. The inside diameters of bearings used in an aircraft landing gear assembly are known to have a standard deviation of o = 0.002 cm. A random sample of 15 bearings has an average inside diameter of 8.2535 cm. a) Test the hypothesis that the mean inside bearing diameter is 8.25 cm. Use a two-sided alternative and a= 0.05. b) Find the P-value for this test. c) Construct a 90% two-sided confidence interval
