Question 208701
There are three hospitals in the Tulsa, Oklahoma, area. The following data show the number 
of outpatient surgeries performed at each hospital last week. At the .05 significance level, 
can we conclude there is a difference in the mean number of surgeries performed by hospital 
or by day of the week? 
Number of Surgeries Performed 
Day St. Luke's St. Vincent Mercy
Monday 14 18 24
Tuesday 20 24 14
Wednesday 16 22 14
Thursday 18 20 22
Friday 20 28 24
--------------------------
I entered the data in 3 lists, then ran ANOVA against the data.
Ho: The means are equal
Ha: At least one is not
----
test statistic: F = 1.802
p-value: 0.2069
-----------------------
Since the p-value is greater than 5%, do not reject Ho.
