I mean, just send it as a reply here,
10.59 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 time (measured from check-in to
when the patient was called into the clinic area) was measured.
The results are stored in ERWaiting .
