A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 146.2-cm and a standard deviation of 1.5-cm. For shipment, 11 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is less than 145.7-cm.
