The melting point of each of 16 samples of a certain brand of hydrogenated vegetable oil was determined, resulting in x = 94.32. Assume that the distribution of the melting point is normal with σ = 1.20. a. Test Hoμ=95 versus Hμ 95 using a two- tailed level .01 test. b. If a level .01 test is used, what is ẞ(94), the probabil- ity of a type II error when µ = 94? c. What value of n is necessary to ensure that ẞ(94) = .1 when a = .01?
