The following fraction nonconforming control chart with n = 100 is used to control a process:
UCL = 0.0750
Center line = 0.0400
LCL = 0.0050
-
(a) Use the Poisson approximation to the binomial to find the probability of a type I error.
-
(b) Use the Poisson approximation to the binomial to find the probability of a type II error, if the true process fraction nonconforming is 0.0600.
-
(c) Draw the OC curve for this control chart.
-
(d) Find the ARL when the process is in control and the ARL when the process fraction nonconform-
ing is 0.0600.

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...
