Step 1

Given a table with data of 3182 participants who developed Hypertension and who do not developed hypertension based on age and gender as shown below.

Relative risk is ratio of probability of event occurring in group 1 to probability of event occurring in group 2.

Step 2

We need to find relative risk for hypertension in women  50+ years versus women < 50 years of age.

Here we can see from the table that out of total 492 50+ years of women 255 women develop hypertension. So probability of hypertension in 50+ years women = 255/492

Here we can see from the table that out of total 115...
