Suppose you enroll 1000 individuals into a cohort study, where exposure of interest is obesity and the outcome of interest is mortality. At baseline, 150 of the obese individuals report having a history of cancer, 150 of the non obese individuals report a history of cancer, and 450 non obese individuals have no cancer history.For the design and the data given below:A) What measure of association could be calculated to describe the relationship between obesity and cancer?B) calculate and interpret.So I did an odds ratio to get:(150/150) divided by (250/450)= 1.79
