Question

1) (6 points) A control group of 370 rats not exposed to the carcinogen develops 20 tumors. Suppose 60 out of 410 rats exposed to a potential carcinogen develop tumors. Based on these data, computed (a) the relative risk, (b) the attributable risk, and (c) the odds ratio. Do these indicators suggest that there is a relationship between exposure and tumor risk?

Step 1

Probability of tumor in exposed group: $$P_{exposed} = \frac{60}{410}$$ Probability of tumor in non-exposed group: $$P_{non-exposed} = \frac{20}{370}$$ $$RR = \frac{P_{exposed}}{P_{non-exposed}} = \frac{\frac{60}{410}}{\frac{20}{370}} = \frac{60}{410} \times Show more…
