A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 130.7-cm and a standard deviation of 0.8-cm. For shipment, 11 steel rods are bundled together. Find the probability that the average length of a randomly selected bundle of steel rods is greater than 131-cm. P(M > 131-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.
