Suppose that during the analyze phase an obvious solution is discovered. Should that solution be immediately implemented and the remaining steps of DMAIC abandoned? Discuss your answer.
Answer to relevant QuestionsConstruct a normal probability plot of the chemical process yield data in Exercise 3.9. Does the assumption that process yield is well modeled by a normal distribution seem reasonable? The bore diameters of eight randomly selected bearings are shown here (in mm): 50.001, 50.002, 49.998, 50.006, 50.005, 49.996, 50.003, 50.004 (a) Calculate the sample average. (b) Calculate the sample standard deviation. The probability distribution of x is f(x) = ke–x,0 ≤ x ≤ . Find the appropriate value of k. Find the mean and variance of x.
