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, standard deviation, and sample size).Compute a t-statistic for independent groups:
mean group 1 = 78.1SD1 = 6.1n1 = 25
mean group 2 = 75.1SD2 = 5.7n2 = 25
What are the degrees of freedom and the value of t ? Using =0.05 for a two-tailed test, is this t statistic significant?Show your calculations (or StatCrunch output) for full credit.
