The weights of a certain brand of candies are normally distributed with a mean weight of 0.8595 g and a standard deviation of 0.0521 g. A sample of these candies came from a package containing 462 candies, and the package label stated that the net weight is 394.5 g. (If every package has 462 candies, the mean weight of the candies must exceed 4620.8539 g for the net contents to weigh at least 394.5 g.) a. If 1 candy is...
