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 1 2 3 4 5 6 7 8 9 10 n 15 15 15 15 15 NUMBER OF DEFECTIVE ITEMS IN THE SAMPLE 3 2 2 2 0 2 1 3 2 1 15 15 15 15 15 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.
