Question 347677: Grand Strand Family Medical Center is specifically set up to treat minor medical emergencies for visitors to the Myrtle Beach area. There are two facilities, one in the Little
River Area and the other in Murrells Inlet. The Quality Assurance Department wishes to
compare the mean waiting time for patients at the two locations. Samples of the waiting
times, reported in minutes, follow:
Location Waiting Time
Little River 31.73 28.77 29.53 22.08 29.47 18.60 32.94 25.18 29.82 26.49
Murrells Inlet 22.93 23.92 26.92 27.20 26.44 25.62 30.61 29.44 23.09 23.10 26.69 22.31
Assume the population standard deviations are not the same. At the .05 significance level,
is there a difference in the mean waiting time?

------------------------------
Ho: u(LR)-u(MI) = 0
H1: u(LR)-u(MI) is not equal to 0
-----------------------------------
I ran a 2-Sample Ttest and got the following:
test statistic: t=1.1047
p-value = 0.2876
---
Since the p-value is greater than 5%, fail to reject Ho.
