The weights of a certain brand of candies are normally
distributed with a mean weight of 0.8541 g and a standard deviation
of 0.0517g. A sample of these candies came from a package
containing 440 candies and the package label stated that the net
weight is 375.6 ( If every package has 440 candies, the mean weight
of the candies must exceed 374 / 440= 0.8536 g for the net contents
to weigh at least 375.6 g)g.)
a. If 1...
