Aprocess that drills holes in crankshafts that are subsequently ground has been found to be in good statistical control, with the following statis-tics used to estimate the mean and the variance of the hole diameter: x =15.050 millimeters r = 0.110 millimeter it is also known that 95% of the hole diameters lie within the range 14.945 to 15.155 millimeters. find the size of the samples employed to produce the ranges r used to estimate the standard deviation of the process. assume that the hole diameters are normally distributed.
