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?
