We have taken 12 samples of 400 book pages found the following proportions of defective pages: .01, .02, .02, .00,.01, .03, .02, .01,.00, .04, .03, and .02. A page is considered defective when one or more errors are detected. a. Calculate the control limits for a p control chart. b. A new sample of 400 pages is taken, and 6 pages are defective. Is the process still in control
