The inspection unit of the manufacturing process is one unit of product. Suppose 20 nonconformities were identified in inspecting 41 units and a control chart is to be set up for this manufacturing process. What are the three-sigma control limits and ?-risk for this control chart? What is the ?-risk and ARL if the average number of nonconformities per unit is two?

A control chart for fraction nonconforming indicates that the current process average is 0.03. The sample size is constant at 200 units. a) Find the three-sigma control limits for the control chart. b) What is the probability that a shift in the process average to 0.08 will be detected on the first subsequent sample? (Hint: use normal approximation) c) What is the probability that this shift will be detected on the second sample taken after the shift?
