A company produces steel rods. The lengths of the steel rods are normally distributed with a mean of 198.9-cm and a standard deviation of 2.3-cm. For shipment, 22 steel rods are bundled together.

Find *P*_{52}, which is the average length separating the smallest 52% bundles from the largest 48% bundles.*P*_{52} = -cm

Step 1

Consider *X* be a random variable which follows normal distribution indicates the lengths of steel rods. T...
