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. Then find the probability of in-control nonconformance given, USL = 4.00995 and LSL = 3.99005 Also, by theory, what is the Probability of an out-of-control point...

2. A process has a X-bar control chart with UCL-17.4. LCL-12.79 using a 3-sigma limit. The subgroup sample size is 3. (a) Estimate the standard deviation of the process, sigma hat. (6 pts) (b) Suppose that the process mean shifts to 13. Find the probability that this shift will be detected on the next sample. (8 pts) (c) Calculate the average run length (ARL) before detecting the shift. (6 pts)

Control charts for bar x chart and S have been maintained on a process and have exhibited statistical control. The sample size is n=6. The control chart parameters are as follows: Estimate the mean and standard deviation of the process. Assume that the process output is well modeled by a normal distribution. If specifications are 703 and 709, estimate the fraction nonconforming. Suppose the process mean shifts to 702.00 while the standard deviation remains constant. What is the probability of...
The I-MR chart is unusual in that the results of individual samples (samples of size 1) are plotted on a chart. In other process control charts it is the mean of larger samples that is plotted. True False If the LCL in U-Chart is negative, it is positioned at zero. True False
