To demonstrate avor aversion learning (that is, learning to dislike a avor that is associated with becoming sick). researchers gave one group of laboratory rats an injection of lithium chloride immediately following consumption of saccharinmflavored water. Lithium chloride makes rats feel sick. A second control group was not made sick after drinking the avored water. The next day. both groups were allowed to drink saccharinflavored water. The amounts consumed (in milliliters) for both groups during this test are given below. Amount Consumed Amount Consumed by Rats That Were by Control Rats Made Sick (n - 4) (n - 4} (a) Test whether or not consumption of saccharinflavored water differed between groups using a 0.05 level of si_nificance.
