Question 181884: Hi,
Can you please help me solve for this problem, it is from Doane−Seward: Applied
Statistics in Business and Economics, ch. 11. My guess was to find the mean of each hospital time. Example: Hospital A 10+19+5+26+11/5 = 14.2
But I feel like there is more to the problem, am I on the right track?
Problem:
The waiting time (in minutes) for emergency room patients with non-life-threatening injuries was measured at four hospitals for all patients who arrived between 6:00 and 6:30 PM on a certain Wednesday. The results are shown below. Research question: Are the mean waiting times the same for emergency patients in these four hospitals?
Emergency Room Waiting Time (minutes)
Hospital A - 10, 19, 5, 26,11
Hospital B - 8, 25, 17, 36
Hospital C - 5, 11, 24, 16, 18, 29, 15
Hospital D - 0, 20, 9, 5, 10, 12
Thank you
