An insurance company wants to design a control chart to monitor whether insurance claim  forms are being completed correctly. The company intends to use the chart to see if  improvements in the design of the form are effective. To start the process, the company  collected data on the number of incorrectly completed claim forms over the past ten days.  The insurance company processes thousands of these forms daily, and due to the high cost  of inspecting each form, only a small representative sample was collected daily. The data is  shown in the following table.  Sample 1 2 3 4 5 6 7 8 9 10  Nos  Inspected  300 300 300 300 300 300 300 300 300 300  No of the  forms  were  completed  incorrectly 10 8 9 13 7 7 6 11 12 8  Design a suitable control chart that can be used by the insurance company using three-sigma  (standard deviation) limits and examine whether the process is in control or out of control
