Refer to the data from a recent prospective cohort study below. Using the rate ratio as a measure of association, which of the following statements refer to the most appropriate inference or conclusion based on the data presented in the table?

	# of participants found to develop CHD	# of participants found not to develop CHD	total
physically inactive	450	750	1200
physically active	50	350	400
total	500	1100	1600

This is a positive association between physical activity and CHD. Persons who are physically active are 3 times as likely to develop CHD compared to those physically inactive.

There is no association between physical activity and CHD.

There is an inverse or indirect association between physical inactivity and risk of CHD and persons who are physically inactive are 1.32 times as likely to develop CHD compared to those physically active.

There is a positive association between physical inactivity and CHD and persons who are physically inactive are 3 times as likely to develop CHD compared to those physically active.

There is a positive association between physical inactivity and CHD and persons who are physically inactive are 4.2 times as likely to develop CHD compared to those physically active.
