An automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are normally distributed with a mean of 116 cm and a standard deviation of 4.8 cm. A. Find the probability that one selected subcomponent is longer than 118 cm. B. Find the probability that if 4 subcomponents are randomly selected, their mean length exceeds 118 cm. C. Find the probability that if 4 are randomly selected, all 4 have lengths that exceed 118 cm.
