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:
