Vаriоus 1Yоu аre interested in risk fаctоrs for colorectal adenomas (pre-cancerous polyps that grow on the lining of the colon and which carry a high risk of cancer). You design a cross-sectional study in which you recruit asymptomatic women at average risk (50 years or older) who are referred to GI clinics for normal colorectal cancer screening. One thousand women enroll and each receives a complete colonoscopy. Prior to the screening procedure, each subject also completes a diet and lifestyle questionnaire and provides a sample of blood.(3 points) Calculate the relevant measure of association mentioned identified in problem 29.
