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 times (measured from check-in to when the patient
was called into the clinic area) were collected and stored
in ERWaiting .
a.	At the 0.05 level of significance, is there evidence of a difference
in the mean waiting times in the four locations?
b.	If appropriate, determine which locations differ in mean
waiting time.
c.	At the 0.05 level of significance, is there evidence of a difference
in the variation in waiting time among the four locations?
