A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 217.3-cm and a standard deviation of 2.3-cm. For shipment, 15 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is between 216.2. cm and 218.9-cm. P(216.2-cm M218.9-cm) - Enter your answer as a number accurate to 4 decimal places. Answers obtained using exact z-scores or z- scores rounded to 3 decimal places are accepted.
