Q2. A researcher wanted to determine whether different brands of cereal lead to different amounts of weight gain. He randomly selected 30 laboratory rats and assigned to five groups. All five groups will have identical lab conditions, with one exception: the brand of cereal that each group receives during the experimental period.
