Determine whether the study is аn оbservаtiоnаl study (O) оr an experiment (E). Identify the explanatory and the response variables. (I) We are interested in learning whether jogging for longer amounts of time decreases the resting heart rate of college students. We want to see if there is a difference between: The resting heart rate of college students that jog for 30 minutes three times a week for six weeks, and The resting heart rate of college students that jog for 15 minutes three times a week for six weeks. To investigate this question, we will use 100 college students who do not currently jog and who have volunteered to participate as subjects in this study. Resting heart rate of each subject will be measured at the start of the study. Fifty of the students will participate in a jogging program where they get together three times a week and jog for 30 minutes. The other 50 students will get together three times a week, but will only jog for 15 minutes. At the end of six weeks, resting heart rate will be measured again.
