Jane is interested in whether regular aerobic exercise reduces cholesterol levels. To examine this question, Jane performs two studies:

Study A: Jane recruits 1,000 participants for the study. When the participant arrives at the lab, they fill out a questionnaire indicating how many hours per week of aerobic exercise they do. They then have blood drawn to check their cholesterol levels.

Study B: Jane puts up flyers looking for participants who rarely exercise. 100 such individuals sign up for her study. All participants first have blood drawn to check their cholesterol levels. Then, Jane randomly assigns half of the participants to the "Aerobic Exercise" group—where the participants have to do 30 minutes of aerobic exercise, three times per week, for six months. The other half of the participants are assigned to the "Stretching" group—where the participants have to do 30 minutes of stretching without any aerobic activity, three times per week, for six months. Finally, after the six months are up, all participants have their blood drawn again to check their cholesterol.

In Study A, Jane finds that there is a correlation of -0.5 between hours of aerobic activity and cholesterol level. From this, she can conclude that: [Insert conclusion or analysis here]

Answer :

Regular aerobic exercise improves cholesterol levels and cardiovascular health. Moderate-intensity physical activity reduces the risk of cardiovascular diseases. Jane's study indicates the positive impact of regular aerobic exercise on cholesterol levels.

Regular aerobic exercise has been linked to improved cholesterol levels by decreasing LDL and increasing HDL levels, reducing the risk of cardiovascular disease. Aerobic activities help maintain cardiovascular health and contribute to lowering overall cholesterol levels.

Studies have shown that individuals engaging in moderate-intensity physical activity can significantly reduce their risk of cardiovascular diseases such as stroke. Recommendations from the American Heart Association highlight the benefits of regular aerobic exercise in maintaining healthy blood pressure and cholesterol levels.

In a study by Jane where a correlation of -0.5 was found between hours of aerobic activity and cholesterol levels, it can be inferred that regular aerobic exercise can help reduce cholesterol levels and improve cardiovascular health.
