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.  Compute a t-statistic for independent groups:

            mean group 1 = 78.1               SD21 = 42.1     n1 = 25

            mean group 2 = 74.1               SD22 = 39.7     n2 = 25

            What are the degrees of freedom and the value of t ? Using α=0.05 for a two-tailed test, is this t statistic significant?  Show your calculations (or StatCrunch output) for full credit.
