A hub and shaft are said to meet satisfactory fit if the clearance between the two is between 0.03 and 0.18 mm. The specifications of the shaft have mean outer diameter of 31.0 mm and a standard deviation of 0.04 mm. The hub specifications have mean inner diameter of 31.1 mm and a standard deviation of 0.03 mm. If 250 shaft and hubs are tested, how many would you expect to exhibit 'satisfactory fit'. Assume hub and shaft are normally distributed. Clearance is Inner diameter - Outer Diameter.
