In the mass production of engine blocks for a single cylinder, the tolerance in the diameter (D) of the cylinders is normally distributed. The average diameter of the cylinders has been measured to be 4 in. and the standard deviation is 0.002 in, what are the probabilities of the following cases? a. A cylinder is measured with D4.002. b. A cylinder is measured with D4.005 C. A cylinder is measured with 3.993 D 4.003 d. If cylinders with deviation from the mean diameter of greater than 20 are rejected, what percent of the blocks will be rejected.
