To study this, a dietician collects data from her patients: she categorizes their blood pressure values into elevated and healthy and she administers a questionnaire from which she is able to classify their diet into high in organic food and low in organic food. The number of patients with high organic food consumption who had elevated and healthy blood pressures were 33 and 74 respectively. The number of patients with low organic food consumption who had elevated and healthy blood pressures were 267 and 395 respectively.
