Acompany produces steel rods. the lengths of the steel rods are normally distributed with a mean of 236.8-cm and a standard deviation of 1.3-cm. for shipment, 29 steel rods are bundled together. find the probability that the average length of a randomly selected bundle of steel rods is between 236.5-cm and 236.7-cm. p(236.5-cm < m < 236.7-cm) =
