8) A control chart for fraction nonconforming

8) A control chart for fraction nonconforming indicates that the current process average is 0.05. The sample size is constant at 250 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 0.09 will be detected on the first subsequent sample? (Hint: Prev = 0.09. Since (Prev = 0.09)
