For a shaft=-bearing assembly, the shaft diameters were found to have an average of 2.2 in., with a standard deviation of 0.12 in., the bearing bore diameters were found to have an average of 2.1 in., with a standard deviation of 0.07., in. What proportion of the assemblies will have a clearance of less than 0.01 in.? Assume that the shaft and bearing dimensions are independent.
