Question

Your assignment is to do a detailed statistical analysis of the data to be able to decide later what would be appropriate control charts to monitor these variables.

The manager provides you data that the office has collected on these two variables:

• Time it takes since the patient checks-in until the patient checks-out
• Number of patients in the waiting room

Present a report to the manager with the results of the statistical analysis of the data and your conclusions on the variables that will be used to monitor the process performance.

Time it takes since the patient checks-in until the patient checks-out
