A hospital administrator has the business objective of reducing the time to process patients' medical records after discharge. She determined that all records should be processed within 5 days of discharge. Thus, any record not processed within 5 days of a patient's discharge 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. Use these data to complete parts (a) through b. Does the process give an out-of-control signal? Explain. OA. Yes, there is an obvious pattern and there are points outside the control limits. O B. Yes, there is an obvious pattern on the control chart. OC. Yes, there are points outside of the control limits.

Yes, there is an obvious pattern on the control chart. O C. Yes, there are points outside of the control limits. O D. No, the process does not give an out-of-control signal. 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. (Round to four decimal places as needed.) (Round to four decimal places as needed.)
