Question: To demonstrate flavor aversion learning (that is, learning to dislike a flavor that is associated with becoming sick), researchers gave one group of laboratory rats an injection of lithium chloride immediately following consumption of saccharin-flavored water. Lithium chloride makes rats feel sick. A control group was not made sick after drinking the flavored water. The next day, both groups were allowed to drink saccharin-flavored water. The amounts consumed (in milliliters) for both groups during this test are given below.

Amount Consumed by Rats                    Amount consumed by
That Were Made Sick(n = 4)                   Control Rats(n = 4)

4                                                                7

5                                                                12

1                                                                8

3                                                                11

(a) Test whether or not consumption of saccharin-flavored water differed between groups using a .05 level of significance. State the value of the test statistic and the decision to retain or reject the null hypothesis.

(b) Compute effect size using eta-squared (n²).
