In а study оf blооd pressure (low, high) аnd use of orаl contraceptive (yes, no), the following data summarizes responses for a sample of women, divided further by age (18-34, 35-49). Age 18-34 High Low Yes 20 200 No 10 150 Age 35-49 High Low Yes 15 60 No 80 480 (3pts) With contraceptive use group "No" viewed as the baseline, calculate and interpret the relative risk of high blood pressure representing the marginal relationship between contraceptive use and blood pressure. (3pts) Now, report the relative risk of high blood pressure representing the conditional relationship between contraceptive use and blood pressure, given age group. Do this for each age group. Explain how these relative risks are interpreted differently from the one above.
