A university counselor believes that hypnosis is more effective than the standard treatment given to the students who have high test anxiety. To test his belief, he randomly divides 22 students with high test anxiety into two groups. One of the groups receives the hypnosis treatment, and the other group receives the hypnosis treatment, and the other group receives the standard treatment. When the treatments are concluded, each student is given a test anxiety questionnaire. High scores on the questionnaire indicate high anxiety. The following are the results: Hypnosis 20 21 33 40 24 43 48 31 22 44 30 Treatment Standard *PPSPPSPFE 42 35 30 53 57 26 37 30 51 62 59 Treatment Using the Mann-Whitney U Test and a = 0.051 tail, would it be valid for the university counselor to conclude that hypnosis treatment is more effective than the standard treatment given to students with high test anxiety?
