A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 242.2-cm and a standard deviation of 1.8-cm. For shipment, 30 steel rods are bundled together.Find the probability that the average length of a randomly selected bundle of steel rods is between 242-cm and 242.9-cm.P(242-cm < M < 242.9-cm) = Enter your answer as a number accurate to 4 decimal places. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
