She determined that all records should be processed within 5 days of discharge. Thus, any record not processed within 5 days of a is nonconforming. The administrator recorded the number of patients discharged and the number of records not processed within the 5- day standard for a 30- day period and stored in MedRec.

a. Construct a p chart for these data.

b. Does the process give an out of control signal? Explain.

c. If the process is out of control, assume that special causes were subsequently identified and corrective action was taken to keep them from happening again. Then eliminate the data causing the out- of- control signals and recalculate the control limits.
