Question: Consider a single sampling plan with Draw the OC curve for
Consider a single-sampling plan with Draw the OC curve for this plan. Now consider chain-sampling plans with Sketch the OC curves for these chain-sampling plans on the same axis. Discuss the behavior of chain sampling in this situation compared to the conventional single-sampling plan with .
Answer to relevant Questionsa. Draw the type-A OC curve for the plan. b. Draw the type-B OC curve for this plan and compare it to the type-A OC curve found in part (a). c. Which curve is appropriate for this situation? Compare the plans developed in Exercise 7.33 in terms of average fraction inspected and their operating-characteristic curves. Which plan would you prefer if? A 24 factorial design has been run in a pilot plant to investigate the effect of four factors on the molecular weight of a polymer. The data from this experiment are as follows (values are coded by dividing by 10). a. ...A process engineer is trying to improve the life of a cutting tool. He has run a 23 experiment using cutting speed (A), metal hardness (B), and cutting angle (C) as the factors. The data from two replicates are shown in ...A component has a Weibull time-to-failure distribution. The value of the scale parameter is Calculate the reliability at 250 hours for the following values of the shape parameter: . For the fixed value of the scale ...
