Question:
A certain product requires that a shaft be inserted into a bearing. Measurements show that the diameter d1 of the cylindrical hole in the bearing is normally distributed with a mean of 3 cm and a variance of 0.0064. The diameter d2 of the shaft is normally distributed with a mean of 2.96 cm and a variance of 0.0036.
a. Compute the mean and the variance of the clearance c = d1 = d2.
b. Find the probability that a given shaft will not t into the bearing. Find the probability that the clearance is negative.
