Unformatted text preview: Looking at the picture, comment on whether the weight of a candy bar might be a Normally distributed random variable. b) Suppose the weight is indeed Normal with the mean and S.D. of the distribution as given by the MINITAB output - what is the probability that a randomly chosen candy bar is within specifications with respect to its weight? Compute this probability using C alcProbability D istributionsN ormal in the MINITAB menus and verify that you get the same value if you use the Normal tables at the back of your text. c) Compare the probability you computed in part (b) against the empirical (based on the sample data) probability estimate you obtained and used in your previous two assignments....
