Question
Suppose we wanted to test the hypothesis that a control group of cancer patients
(Group 1) would report higher mean pain ratings than an experimental group
receiving special massage treatments (Group 2). Use the following information.
mean group 1 = 78.5
mean group 2 = 72.1
s21 = 42.1
s2 = 39.7
ni = 25
n3=25
Compute a t-test for independent groups:
Using a=0.05 for a one-tailed test, is the t statistic significant?
Write one or two sentences (in plain English/non-statistical terms) that
could be used to report the results obtained for the t-test.
