Construct an EWMA chart on the residuals from the model you fit in part (c) of that exercise. (Use =0.2) Problem4: Consider the original concentration data in Exercise 10.20. Set up a batch means control chart with batch size equal to 5. s Problem5: For this problem do NOT use software to solve the problem. You can use calculator. Consider the data in the following table. a) Calculate sample autocorrelation function b) Fit a firstorder autoregressive model t t t x x 1 to the data. Set up an individuals control chart on the residuals of this model. c) Construct an EWMA chart on the residuals based on =0.2. t Xt 1 487 2 549 3 505 4 319 5 201 6 178 7 123 8 299 9 211 10 240...
