An exercise physiоlоgist is interested in the effect оf аerobic exercise on blood pressure in heаlthy elderly people. One hundred heаlthy elderly subjects randomly selected from a Phoenix-area retirement community answered questions about their exercise habits and had their blood pressure measured. The researcher found that 44 of the 100 subjects regularly participate in aerobic exercise, while 56 subjects do not. The findings were that systolic blood pressure of those who do participate in aerobic exercise tends to be lower than it is for those who do not participate in aerobic exercise. Is this a randomized experiment, non-randomized experiment, or observational study?
