For #10 - 19: A researcher conducts an Independent-Measures study examining the effectiveness of a group exercise program on muscle strength at an assisted living facility for elderly adults. One group of residents is selected to participate in the new weight training program and a second group participates in a fitness walking group. After 8 weeks, the researcher records a strength score for each individual. The data are as follows: Strength Group n = 14 Walking Group n = 28 Here are some formulas and values to help: Pooled Variance (s?,) = 14 S(M,-M2) M, = 15 M2 = 12 п n2 t = M, - M2 / S (M1-M2) 15. Do the t-test. What is your conclusion? Do you reject the null hypothesis or fail to reject the null hypothesis?
