Consider the temperature data in exercise 10.24. Set up an EWMA 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 chart is sued to maintain current control of a process. A single assignable cause of magnitude 2σ occurs, and the time that the process remains in control is an exponential random variable with mean 100 hr. Suppose ...Consider the group control charts constructed in Exercise 10.5. Suppose the next ten samples are in Table 10E.5. Plot the new data on the control charts and discuss your findings. Consider the first three process variables in Table 11.5. Calculate an estimate of the sample covariance matrix using both estimators S1 and S2 discussed in Section 11.3.2. Consider the p = 4 process variables in Table 11.6. After applying the PCA procedure to the first 20 observations data (see Table 11.7), suppose that the first three principal components are retained.Post your question
