A machine that produces ball bearings has initially been set so that the mean diameter of the bearings it produces is 0.500 inch
es. A bearing is acceptable if its diameter is within 0.005 inches of this target value. Suppose, however, that the setting has changed during the course of production, so that the distribution of the diameters produced is now approximately normal with mean 0.498 inch and standard deviation 0.002 inch. What percentage of the bearings produced will not be acceptable?
