10 samples of 15 each were taken from an ongoing process to establish a p-chart for control. The sample and the number of defectives in each are shown in the following table Sample N # of defective 1 15 2 2 15 1 3 15 1 4 15 1 5 15 1 6 15 0 7 15 2 8 15 1 9 15 3 10 15 0 A.) Determine the p, Sp, UCL and LCL for P-chart of 95% confidence (1.96 standard deviations). (Leave no cells blank. Round up any negative LCL value to 0. 3 decimal places) B.) what comments can you make about the process? C.) Is Process is out of statistical control or on statistical control?
