Precision manufacturing: A process manufactures ball bearings with diameters that are normally distributed with mean 24.3 millimeters and standard deviation 0.08 millimeters. (a) What proportion of the diameters are less than 24.2 millimeters? (b) What proportion of the diameters are greater than 24.5 millimeters? (c) To meet a certain specification, a ball bearing must have a diameter between 24 and 24.5 millimeters. What proportion of the ball bearings meet the specification? Round the answers to at least four decimal places.
