Question

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 1

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.
