Question

"a) Compute the absolute risk reduction for a smoker compared to a non-smoker.

b) Compute the relative risk for a smoker compared to a non-smoker. Round to two decimal places. Show work."

Answer 1

The absolute risk reduction for a smoker compared to a non-smoker is 10%, while the relative risk is 3.

Step-by-step explanation:

To calculate the absolute risk reduction, we need to determine the difference in risk between smokers and non-smokers. Let's say the incidence of a health event among non-smokers is 5% and the incidence among smokers is 15%. The absolute risk reduction would be the difference between these two percentages: 15% - 5% = 10%.

To calculate the relative risk, we need to divide the incidence of the health event in the exposed group (smokers) by the incidence in the non-exposed group (non-smokers). In this case, it would be 15% / 5% = 3.
