An exercise advocate wants to determine the relationship between walking rigorously and weight loss. He recruits participants to engage in a weeklong study. He instructs participants to take a brisk walk as many days of the week as possible for as long as they can. Participants will record the following data: weight prior to engaging in the walking regimen, the amount of time walked each day, and their weight at the end of the week. Participants will submit their data to the exercise advocate at the end of the week. The exercise advocate will preprocess the data to derive the total number of hours walked (walkhrs) and the change in weight for each participant (wtloss = weight at the beginning of the week – weight at the end of the week).
Determine the relationship between walking rigorously and weight loss.
