A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 190.4-cm and a standard deviation of 1.5-cm. For shipment, 28 steel rods are bundled together. Find P29, which is the average length separating the smallest 29% bundles from the largest 71% bundles. P29 = -cm Enter your answer as a number accurate to 2 decimal place. Answers obtained using exact z-scores or z-scores rounded to 3 decimal places are accepted.
