The weights of a certain brand of candies are normally distributed with a mean weight of 0.8599 g and a standard deviation of 0.0514 g. A sample of these candies came from a package containing 447 candies, and the package label stated that the net weight is 381.7 g. (If every package has 447 candies, the mean weight of the candies must exceed 381.7/447= 0.8539 g for the net contents to weigh at least 381.7 g.) a. If 1 candy is randomly selected, find the probability that it weighs more than 0.8539 g. b. If candies are randomly selected, find the probability that their mean weight is at least 0.8539 g. The probability that a sample of candies will have a mean of g or greater is..
