Question: Reconsider the data in Exercise 9 4 Suppose the data there
Reconsider the data in Exercise 9.4. Suppose the data there represent observations taken immediately after a process adjustment that was intended to reset the process to a target of µ0 = 8.00. Set up and apply an FIR CUSUM to monitor this process.
Relevant QuestionsThe data in Table 9E.3 are temperature readings from a chemical process in C, taken every two minutes. (Read the observations down, from left.) The target value for the mean is 0 = 950. (a) Estimate the process ...Consider a modified control chart with center line at µ = 0 and σ = 1.0 (known). If n = 5, the tolerable fraction nonconforming = 0.00135, and the control limits are at three-sigma, sketch the OC curve for the chart. ...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.

Set up a CUSUM control chart on the residuals from the model you fit to the data in part (c) of that exercise.
