Suppose that a team of psychologists has recommended that people who experience anxiety attacks should receive regular counseling. The psychologists claim that the counseling sessions provide a therapeutic, or healing, experience. The psychologists promote this type of therapy rather than pharmaceutical treatments. To test the effectiveness of counseling, a researcher randomly selects six people who experience anxiety attacks. These six people are interested in the counseling treatment. The researcher gives each person an anxiety test before and after the person has a counseling session with a therapist. Higher scores on the test indicate a higher level of anxiety in the person taking the test. The anxiety test scores are normally distributed. The test scores of the six people are shown in the table below. Person 1 2 3 4 5 6 Pre-Counseling Score 66 71 80 85 85 90 Post-Counseling Score 64 65 79 81 81 91 A)What does the Null hypothesis say about the mean difference in post-counseling and pre-counseling scores?
