A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 193.5-cm and a standard deviation of 2.1-cm. For shipment, 10 steel rods are bundled together. Round all answers to four decimal places if necessary. What is the distribution of X X? X X ~ N(,) What is the distribution of ¯ x x¯? ¯ x x¯ ~ N(,) For a single randomly selected steel rod, find the probability that the length is between 193.8-cm and 194.2-cm. For a bundled of 10 rods, find the probability that the average length is between 193.8-cm and 194.2-cm. For part d), is the assumption of normal necessary? NoYes
