Didi's assembly unit has decided to use a p-Chart to monitor the proportion of defective steel handles produced by their production process. The control limits on these charts will be designed to include 98% of the sample proportions when the process is In Control. The quality control manager randomly samples 100 steel handles at 6 successive time periods and counts the number of defective handles in the sample. Sample 1 2 3 4 5 6 Average Defects 10 12 8 11 13 12 11 What is the Center Line of the p control chart
