Reconsider the data in Exercise 9.9. Set up and apply an EWMA control chart to these data using = 0.1 and L = 2.7.
Answer to relevant QuestionsAnalyze the data in Exercise 9.1 using a moving average control chart with w = 6. Compare the results obtained with the cumulative sum control chart in Exercise 9.1. w = 6, 0 = 1050, = 25, CL = 1050, UCL = 1080.6, ...Show that if = 2/(w + 1) for the EWMA control chart, then this chart is equivalent to a w-period moving average control chart in the sense that the control limits are identical in the steady state. Consider the valve failure data in Example 7.6. Set up a one-sided CUSUM chart for monitoring and detecting an increase in failure rate of the valve. Assume that the target value of the mean time between failures is 700 ...Use the data in Table 10E.1 to set up short-run charts using the DNOM approach. The nominal and x R dimensions for each part are TA = 100, TB = 60, TC = 75, and TD = 50. Consider the molecular weight data in Exercise 10.16. Construct a EWMA control chart on the residuals from the model you fit to the data in part (c) of that exercise. Let = 0.1 and L = 2.7 (approximately the same as a ...
