    4. (5 Points) Control charts are to be kept on the thickness measurements for the process that produces steel tubing. The current specifications on the tubing are 0.1340 +0.0010 inch. After collecting 25 rational samples of size n 4 measurements at approxi half-hour intervals, the data were used to determine the sum of sample averages as 4.014 inches and the sum of sample ranges as 0.027 inch. Using X-bar and R control charts the process was declared in-control. Assume that...

    Problem 6 [Pencil version] X-bar and R charts with n= 4 were established with the centerlines of 10 and 2, respectively. Both charts didn't show any out-of-control signals. In other words, both process mean and variability were in statistical control. You just noticed an hour ago, however, that the process mean shifted to 14 and the process mean ended up being in out of control, while the process variability remains the same. In summary, Mo = 10, Mshifted = 14,...
