company produces steel rods. The lengths of the steel rods are normally distributed with a mean of189.6-cm and a standard deviation of 2.1-cm. For shipment, 18 steel rods are bundled together. Round allanswers to four decimal places if necessary.a. What is the distribution of X? X - N(b. What is the distribution of x? - N(c. For a single randomly selected steel rod, find the probability that the length is between 189.1-cmand 189.6-cm.d. For a bundled of 18 rods, find the probability that the average length is between 189.1-cm and189.6-cm.

According to guidelines we solve only first three subparts when given multiple subparts.
