Consider the control chart in Exercise 7.26. Find the average run length if the process fraction nonconforming shifts to 0.20. A process has an in-control fraction nonconforming of p = 0.02. What sample size would be required for the fraction nonconforming control chart if it is desired to have a probability of at least one nonconforming unit in the ...A fraction nonconforming control chart with n = 400 has the following parameters: UCL = 0.0962; Center line = 0.0500; LCL = 0.0038. (a) Find the width of the control limits in standard deviation units. (b) Suppose the ...Consider the paper-making process in Exercise 7.49. Set up a u chart based on an average sample size to control this process. In Exercise 7.49 Find the three-sigma control limits for (a) a c chart with process average equal to nine nonconformities. (b) a u chart with c = 16 and n = 4.Post your question
