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,...

1. Design X-bar and R charts a control chart with "standards given" as an aimed-at mean of Xo 4.0, Sigma 0033, and Subgroup size 5. It is not necessary to sketch the control-chart since we have no points to put on it. Just specify, CL, UCL and LCL. That is the design. 2. Then find the probability of in-control nonconformance given, USL 4.00995 and LSL = 3.99005 3. Also, by theory, what is the Probability of an out-of-control point when...
