Researchers are working with a cohort of 1,313 people. They waited couple years to see which ones would expose themselves to some possibly harmful thing and 851 of them did. The other 462 did not have (report) the exposure. Then they waited a few more years and observed which people got the disease and which did not. The following table summarizes the results.

No disease Got disease Total

Not exposed 308 154 462

Exposed 142 709 851

Total 450 863 1313

a. Compute the odds ratio for getting the disease. Interpret this odds ratio in words to answer the question ‘Whether a certain disease is associated with a certain exposure?'

b. Calculate the Relative Risk. Interpret this result.
