Answer:
A) 0.83 for lung cancer and 0.18 for coronary thrombosis.
Explanation:
For the population etiologic fraction due to smoking, we use the formula:
For lung cancer:
Given:
We first find RRs which is the relative risk of dying from cancer for a smoker compared to a non smoker.
= 10.1429
Therefore population etiologic fraction due to cancer wil be:
= 0.8341
Population etiologic fraction of cancer due to smoking is 0.834
•For coronary thrombosis:
Let's use the formula:
Let's first find the RRs (relative risk of dying from cornary thrombosis for a smoker compared to a non smoker)
The population etiologic fraction of cornary thrombosis due to smoking, will be:
= 0.187
The population etiologic fraction of cornary thrombosis due to smoking is 0.187
Therefore the answer is option (A) 0.83 for lung cancer and 0.18 for coronary thrombosis
