The Woods worth Publishing Company produces millions of books containing hundreds of millions of pages each year. To ensure the quality of the printed page, Woods worth uses statistical process control. In each production run, 1,000 pages are randomly inspected. The examiners look for print clarity and whether the material is centered on the page properly. The numbers of defective pages in the last 40 production runs are listed here. Draw the p chart. Using the pattern tests, can we conclude that the production process is under control?
