A psychologist is interested in whether hypnosis affects brain dominance (that is, whether the left or right hemisphere of the brain is dominant). Eleven college students from the freshman elass are randomly sampled for an experiment. The experiment has two conditions that are given on different days. In condition 1, the students are hypnotized and then given a test that measures the relative dominance of the right and left hemispheres. The higher the score, the more dominant is the right hemisphere. In condition 2, the same students are given the test again, only this time they are not hypnotized but are in their normal state of consciousness. The following seores are obtained: Student 23 10 11 Condition 1 26 15 22 19 23 37 16 17 14 16 21 Condition 2 12 16 18 17 21 22 11 22 10 14 15 A. What is the power of this experiment, for a - 0.052 tail and Preal .10?
