An automatic machine in a manufacturing process is operating properly if the lengths of an important subcomponent are normally distributed with a mean of 112 cm and a standard deviation of 4.9 cm. A. Find the probability that one selected subcomponent is longer than 114 cm. Probability= B. Find the probability that if 3 subcomponents are randomly selected, their mean length exceeds 114 cm. Probability= C. Find the probability that if 3 are randomly selected, all 3 have lengths that exceed 114 cm. Probability= RECALL: Part (a) is a review of Chapter 6, and part (c) will be your answer to part (a) raised to the power of 3 since it must occur all 3 times.
