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 treatm ents are concluded, each student is given a test anxiety questionnaire. High scores on the questionnaire indicate high anxiety. The following are the results: Нуpпosis 20 21 33 40 24 43 48 31 22 44 30 Treatment Standard 42 35 30 53 57 26 37 30 51 62 59 Treatment
