A line produces leather jackets. Once each hour a jacket is selected at random from those made during that hour. Small imperfections (missed stitches, zipper catch, button missing, loose threads) are counted. Recent data show an average of eight imperfections (nonconformities) in each sample. Using the formulas for a c chart, calculate the control limits and centerline for this situation. If management wants a process capability of four nonconformities per sample, will this line be able to meet that requirement
