Alabama Industries has decided to use ap-Chart with 2-sigma control limits to monitor the proportion of defective steel bars produced by their production process. The quality control manager randomly samples450 steel bars at12successively selected time periods and counts the number of defective steel bars in the sample.

Step 1 of 8:What is the Center Line of the control chart? Round your answer to three decimal places.

Step 2 of 8:What value ofzshould be used to construct the control chart?

Step 3 of 8:What is the Upper Control Limit? Round your answer to three decimal places.

Step 4 of 8:What is the Lower Control Limit? Round your answer to three decimal places.

Step 5 of 8:At the next time period,450 steel bars are sampled and14 defective steel bars are detected.

Step 6 of 8:At the next time period,450 steel bars are sampled and28 defective steel bars are detected.

Step 7 of 8:At the next time period,450 steel bars are sampled and32 defective steel bars are detected.
