To demonstrate flavor aversion learning (that it, learning to dislike a flavor that is associated with becoming sick), researchers gave one group of lab 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 millimeters) for both groups during this test are given here. Amount consumed by rats that were made sick (n=4). 4, 5, 1, 3. Amount consumed by control rats (n=4) 7, 12 ,8, 11 A) test whether or not the 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 the effect size using eta-squared ( beta 2 )
