An automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are normally distributed with mean = 112 cm and standard deviation = 5.5 cm. (a) Find the probability that one selected subcomponent is longer than 117 cm. (Round your answer to four decimal places.) (b) Find the probability that if four subcomponents are randomly selected, their mean length exceeds 117 cm. (Round your answer to four decimal places.) (c) Find the probability that if four subcomponents are randomly selected, all four have lengths that exceed 117 cm. (Round your answer to four decimal places.)
