The accounts receivable department at Rick Wing Manufacturing has been having difficulty getting customers to pay
the full amount of their bills. Many customers complain that the bills are not correct and do not reflect the materials that
arrived at their receiving docks. The department has decided to implement SPC in its billing process. To set up control
charts, 10 samples of 100 bills each were taken over a month's time and the items on the bills checked against the bill
of lading sent by the company's shipping department to determine the number of bills that were not correct. The results
