. The probability density function for the diameter of a drilled hole in millimeters is 10 e 10(x-5) for x>5 mm. Although the target diameter is 5 millimeters, vibrations, tool wear, and other nuisances produce diameters greater than 5 millimeters. a. Determine the variance of the diameter of the holes. (Please refer to your books) b. Determine the cumulative distribution function.
