The weights of a certain brand of candies are normally distributed with a mean weight of 0.8549 g and a standard deviation of 0.052 g. A sample of these candies came from a package containing 452 candies, and the package label stated that the net weight is 386.1g. (If every package has 452 candies, the mean weight of the candies must exceed StartFraction 386.1 Over 452 EndFraction =0.8541 g for the net contents to weigh at least 386.1g.) a. If...

Ch 7 # 5: Please help answer the probability for a-e: A small hair salon in Denver, Colorado, averages about 60 customers on weekdays with a standard deviation of 15. It is safe to assume that the underlying distribution is normal. In an attempt to increase the number of weekday customers, the manager offers a $4 discount on 7 consecutive weekdays. She reports that her strategy has worked since the sample mean of customers during this 7 weekday period jumps...
