how to solve

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 99.3- cm and a standard deviation of 1.7 cm. For shipment, 10 steel rods are buridled together. Round all answers to four decimal places if necessary. a. What is the distribution of X? X - N b. What is the distribution of I? a - N c. For a single randomly selected steel rod, find the probability that the length is between 99.6-cm and 99.9.cm. d. For a bundled of 10 rods, find the probability that the average length is between 99.6-cm and 99.9 cm. e. For part d), is the assumption of normal necessary? ( Not Yes
