Suppose that we were going to conduct a study to determine if there is an decrease in risk of getting lung cancer based on whether the person eats strawberries several times a week. In the group (1) that eats strawberries regularly, we find than 5 out of 2000 get lung cancer. In the group (2) that does not eat strawberries regularly, we find that 5 out of 1000 get lung cancer. What is the sample relative risk?

A. 0.0025

B. 0.05

C. 0.5

D. 0.025

Answer: Option C

Step-by-step explanation:

In group (1), the risk is = 5/2000 x 100

= 0.25

In group (2), the risk is = 5/1000 x 100

= 0.5

The sample relative risk is = 0.25/0.5

= 0.5

So, option C is correct.
