Peanut allergies are becoming increasingly common in Western countries. Some evidence points to the timing of peanuts' firstintroduction in the diet as an influential factor, raising the question of whether pediatricians should recommend early exposure oravoidance. A study enrolled infants with a diagnosed peanut allergy and randomly assigned them to either completely avoidpeanuts or consume peanuts in small amounts regularly until they reached 60 months of age. At the end of the study, 18 of the 51infants who had avoided peanuts were still allergic to peanuts. In contrast, five of the 47 infants who had consumed peanuts werestill allergic to peanuts.(a) What are the two variables described?
