A critical factor in the successful operation in today’s hospital system is the effective staffing of emergency room (ER) personnel. In an effort to examine this issue, Wilmington Hospital would like to determine if the average number of emergency room visits differs across the hospital’s three eight hour shifts during the day. The following table represents the number of ER visits for randomly selected eight hour shifts. These data can also be found in the Excel file Wilmington Hospital.xlsx.
Using α = 0.05, perform a hypothesis test to determine if there is a difference in the number of ER visits during the three shifts.
