A manufacturer has been sampling output from a process to help measure the number of defective items the process is producing. The quality manager has taken 20 samples of 50 items each (each sample contains 50 observations), and has found a total of 35 defective items in all of the samples Given this data, what would be the lower and upper control limits for a p-chart of this process if the limits are based on 3 standard deviations (2-3)? (Carry to 4 decimal places in your computations.) Upper controllimit = 0.1764 a. Lower control limit = 0.0000 Upper controllimit = 0.1130 b. Lower controllimit = 0.0000 Upper controllimit = 0.1130 c. Lower controllimit -0.0430 Upper controllimit = 0.0792 d. Lower control limit= .0008 Upper controllimit = 0.1417 e. Lower controllimit=0.0000
