A process is being controlled with a fraction nonconforming control chart. The process average has been shown to be 0.07. Three-sigma control limits are used, and the procedure calls for taking daily samples of 400 items. ...Analyze the data in Exercise 7.29 using an average sample size. In Exercise 7.29
