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 = 79.1 SD 2 1 = 42.1 n1 = 25 mean group 2 = 74.1 SD 2 2 = 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 show stat crunch or excel.
