        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   .                 At the 0.05   level of significance, is there evidence of a difference   in the mean   waiting times in the four locations?              If   appropriate, determine which locations differ in mean    waiting   time.                 At the 0.05   level of significance, is there evidence of a difference   in the   variation in waiting time among the four locations?
