Ten samples of 15 parts each were taken from an ongoing process to establish a p-chart for control. The samples and the number of defectives in each are shown in the following table: SAMPLE n 15 2 15 1234567899 15 15 15 15 15 10 15 15 7 15 P Sp UCL LCL 15 15 NUMBER OF DEFECTIVE ITEMS IN THE SAMPLE 0 2 3 1 3 1 0 0 0 a. Determine the p, Sp, 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. Round your answers to 3 decimal places.) b. What comments can you make about the process?
