A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 128.3-cm and a standard deviation of 2.2-cm. For shipment, 7 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is between 128.9- cm and 129.7-cm. P(128.9-cm < M < 129.7-cm) =
