Question

A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 165.4-cm and a standard deviation of 1.5-cm. For shipment, 18 steel rods are bundled together.

Find *P*_{49}, which is the average length separating the smallest 49% bundles from the largest 51% bundles.*P*_{49} = -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.
