12.4 The data in Table EX 12.4 records the number of clinician electronic medical record (EMR) data entry errors in a long-term acute care facility collected as part of a sampling study. Samples of 500 data entries were used.

Using a 95.5 percent confidence level, determine the control limits for an appropri- ate control chart. Construct an appropriate control chart and identify any observations that are not within control limits. 12.4 The data in Table EX 12.4 records the number of clinician electronic medical record (EMR) data entry errors in a long-term acute care facility collected as part of a sampling study.
