A belt that is used in a drive mechanism in a copier machine is required to have a minimum tensile strength of LSL = 150 lb. It is known from long experience that σ = 5 lb for this particular belt. Find a variables sampling plan so that p1 = 0.005, p2 = 0.02, α = 0.05, and β = 0.10. Assume that Procedure 1 is to be used.
Answer to relevant QuestionsSuppose 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. Consider the concentration of suspended solids from Exercise 3.17. Assume that reading across, then down, gives the data in time order.
