STATS HELp?

Question

Suppose that we were going to conduct a study to determine if there is an increased risk of getting lung cancer based on whether the person eats strawberries several times a week. In our eats strawberries regularly group(1), we find than 5 out of 2000 get lung cancer. In our non strawberry eating regular group(2), we find that 5 out of 1000 get lung cancer. What is the sample relative risk? (Give to one decimal place.)

Answer 1

It looks like you want to compare two binomial distributions:

1. p=5/2000
2. p=5/1000

I'm not familiar with the terminology of 'relative risk'. What is that?
