A hospital conducted a study of the waiting time in its emergency room. The hospital has a main
campus and three satellite locations. Management had a business objective of reducing waiting
time for emergency room cases that did not require immediate attention. To study this, a random
sample of 15 emergency room cases that did not require immediate attention at each location
were selected on a particular day, and the waiting times (measured from check-in to when the
patient was called into the clinic area) were collected and stored in ERWaiting. The hospital
decides to perform an ANOVA F test to find at the 0.05 level of significance, if there is evidence
of a difference in the mean waiting times in the four locations.
