A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 163.1-cm and a standard deviation of 1.6-cm. For shipment, 10 steel rods are bundled together. Round all answers to four decimal places if necessary. For a single randomly selected steel rod, find the probability that the length is between 163.2-cm and 163.8-cm.For a bundled of 10 rods, find the probability that the average length is between 163.2-cm and 163.8-cm
