Peanut allergies are becoming increasingly common in Western countries. Some evidence points to the timing of peanuts' first introduction in the diet as an influential factor, raising the question of whether pediatricians should recommend early exposure or avoidance. A study enrolled infants with a diagnosed peanut allergy and randomly assigned them to either completely avoid peanuts or consume peanuts in small amounts regularly until they reached 6060 months of age. At the end of the study, 1818 of the 5151 infants who had avoided peanuts were still allergic to peanuts. In contrast, 55 of the 4747 infants who had consumed peanuts were still allergic to peanuts.
Required:
a. What are the two variables described?
b. How many infants do these data represent?
c. How many of them were assigned to avoid peanuts during the study?
