# Question

The data shown in Table 10E.10 are temperature measurements made every 2 minutes on an intermediate chemical product (read down, then across from left to right).

(a) Calculate the sample autocorrelation function. Interpret the results that you have obtained.

(b) Construct an individuals control chart, using the moving range method to estimate the standard deviation. Interpret the results you have obtained.

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 ...Discuss how you would use a CUSM in the short production-run situation. What advantages would it have relative to a Shewhart chart, such as a DNOM version of the x chart? A machine has four heads. Samples of n= 3 units are selected from each head, and the x and R values for an important quality characteristic are computed. The data are shown in Table10E.4. Set up group control charts for this ...Consider the first two 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. Using the residuals from the regression models in Exercise 11.19, set up EWMA control charts. Compare these EWMA control charts to the She whart charts for individuals constructed previously. What are the potential ...Post your question
