Use the data in Table 10E.2 to set up appropriate short-run x and R charts, assuming that the standard deviations of the measured characteristic for each part type are not the same. The nominal dimensions for each part are TA = 100, TB = 200, and TC = 2000.
Answer to relevant QuestionsThe data shown in Table 10E.9 are concentration readings from a chemical process, made every 30 minutes (read down, then across from left to right). (a) Calculate the sample autocorrelation function and provide an ...Consider the temperature data in exercise 10.24. Set up a CUSUM control chart on the residuals from the model you fit to the data in part (c) of that exercise. Compare it to the individuals chart you constructed using the ...An x chart is used to maintain current control of a process. The cost parameters are a1 = $0.50, a2 = $0.10, a3 = $25, a′3 = $50, and a4 = $100. A single assignable cause of magnitude δ = 2 occurs, and the duration of the ...The x and R values for 20 samples of size 5 are shown in Table 10E.6. Specifications on this product have been established as 0.550 ± 0.02. (a) Construct a modified control chart with three-sigma limits, assuming that if ...Suppose that there are p = 4 quality characteristics, and in correlation form all four variables have variance unity and that all pairwise correlation coefficients are 0.9. The in-control value of the process mean vector ...
