Question
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 the table.
a) At the 0.05 level of significance, is there evidence of a difference in the mean waiting times in
the four locations?
