a. Determine the %media:formula221.mml%, S_p, UCL and LCL for a p-chart of 95 percent confidence (1.96 standard deviations). Leave no cells blank - be certain to enter "0" wherever required. If you round for intermediate steps, go to at least 3 decimal places (so .0426 is rounded to .043), and round your final answers to 3 decimal places.
