Random samples of size n = 410 are taken from a population with p = 0.09.
Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the p¯p¯ chart. (Round the value for the centerline to 2 decimal places and the values for the UCL and LCL to 3 decimal places.)
Calculate the centerline, the upper control limit (UCL), and the lower control limit (LCL) for the p¯p¯ chart if samples of 290 are used. (Round the value for the centerline to 2 decimal places and the values for the UCL and LCL to 3 decimal places.)
Case I: Center line =0.09 , Upper control Limit (UCL) = 0.132 , Lower Control limit (LCL) = 0.047.
Case 2 : Center line =0.09 , Upper control Limit (UCL) = 0.140 , Lower Control limit (LCL) = 0.039
