Question: Raloff (1995) reported on a study conducted by Dimitrios Trichopolous of the Harvard School of Public Health in which researchers "compared the diets of 820 Greek women with breast cancer and 1548 others admitted to Athens-area hospitals for reasons other than cancer." One of the results had to do with consumption of olive oil, a staple in many Greek diets. The article reported that "women who eat olive oil only once a day face a 25 percent higher risk of breast cancer than women who consume it twice or more daily."

a. The increased risk of breast cancer for those who consume olive oil only once a day is 25%. What is the relative risk of breast cancer for those who consume olive oil only once a day, compared to those who eat it twice or more?

b. What information is missing from this article that would help individuals assess the importance of the result in their own lives?
