Assume that the mean of the engineered part is 79.95 andstandard deviation of 0.017291, with a lower specification limit of79.9 and upper specification limit of 80.
a. Determine the probability that a part is defective.
b. Suppose that 1,000,000 parts are produced, what is theexpected number of defective units? This is equivalent to findingthe PPM (parts per million).
