Question

11

For #10 - 19: A researcher conducts an Independent-Measures study examining the effectiveness of a 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: group Strength Group n = 14 Here are some formulas and values to help: Pooled Variance (s?,) = 14 Walking Group n = 28 ,2 S S(M,-M2) + M1 = 15 M2 = n2 t = M1 - M2 / s (M1-M2) = 12 %3D 11. Calculate your estimated standard error (SM1- m2).
