Math Problem Statement
company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 241.4-cm and a standard deviation of 0.6-cm. For shipment, 5 steel rods are bundled together.
Find the probability that the average length of a randomly selected bundle of steel rods is between 241.7-cm and 241.9-cm. P(241.7-cm < M < 241.9-cm) =
