The Director of Radiology at a large hospital is concerned about the scheduling of the radiology facilities. On average, 250 patients are transported per day (8 hours) to the Radiology Department for diagnostic procedures. If the patients do not reach their radiology unit at their scheduled time, backlogs will occur and other patients will experience delays. The time it takes to transport patients from ward to the radiology unit was operationally defined as the time between when the transporter was assigned to the patient and the time the patient arrived at the radiology unit. A sample of n = 4 patients was selected each day for 5 days and the time to transport each patient in minutes, was measured (Gitlow et al.). The data is shown in the table below. On average, how many patients are being transported?
