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?’
