# Question

Tale 7E.1 contains data on examination of medical insurance claims. Every day 50 claims were examined.

(a) Set up the fraction nonconforming control chart for this process. Plot the preliminary data in Table 7E.1 on the chart. Is the process in statistical control?

(b) Assume that assignable causes can be found for any out-of-control points on this chart. What center line and control limits should be used for process monitoring in the next period?

Analyze the data in Exercise 7.29 using an average sample size. In Exercise 7.29 A process has an in-control fraction nonconforming of p = 0.01. The sample size is n = 300. What is the probability of detecting a shift to an out-of-control fraction nonconforming of p = 0.05 on the first sample following ...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 ...The number of nonconformities found on final inspection of a tape deck is shown in Table 7E.14. Can you conclude that the process is in statistical control? What center line and control limits would you recommend for ...Find 0.980 and 0.020 probability limits for a control chart for nonconformities per unit when u = 6.0 and n = 3. u chart with u = 6.0 and n = 3. c = u n = 18.
