A machining operation produces bearings with diameters that are normally distributed
Chapter 4, Problem 4.66(choose chapter or problem)
A machining operation produces bearings with diameters that are normally distributed with mean 3.0005 inches and standard deviation .0010 inch. Specifications require the bearing diameters to lie in the interval 3.000.0020 inches. Those outside the interval are considered scrap and must be remachined. With the existing machine setting, what fraction of total production will be scrap? a Answer the question, using Table 4, Appendix 3. b Applet Exercise Obtain the answer, using the applet Normal Probabilities.
