The melting point of each of 16 samples of a certain brand of hydrogenated oil was determined, resulting in f 2 94.32. Assume that the distribution of the melting point is normal with o = 1.20. a. Test Ho: u = 95 versus Ha: p at 95 using a two tailed level 0.01 test. b. If a level 0.01 test is used, what is [3(94), the probability of a type II error when u = 94? c. What value of n is necessary to ensure that [3(94) = .1 when d = 0.01
