The melting point of each of 16 samples of a certainbrand
Chapter 8, Problem 19(choose chapter or problem)
The melting point of each of 16 samples of a certainbrand of hydrogenated vegetable oil was determined,resulting in x 5 94.32. Assume that the distribution ofthe melting point is normal with s 5 1.20.a. Test H0: m 5 95 versus Ha: m 95 using a twotailedlevel .01 test.b. If a level .01 test is used, what is b(94), the probabilityof a type II error when m 5 94?c. What value of n is necessary to ensure that b(94) 5 .1when a 5 .01?
