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 Walking Here are some formulas and values to help: Pooled Variance (s?,) = 14 Group Group n = 28 n = 14 S(M,-M2) + M1 n2 t = M1 - M2 / S (M1-M2) = 15 M2 = 12 14. Using two tails, an alpha level of .05 and the df you calculated above in #13, what is your teritical? (Hint: If you have an in-between value on the Table of Values, just use the next largest df value-beneath where it would have been found in the table.
