An educational psychologist is concerned about the effect of test anxiety on exam performance. The psychologist selects a random sample of 4 people who report suffering from extreme test anxiety and asks them to read and study a chapter of a textbook. After 3 hours of study time, they are given a 10 question quiz on the material. Then, the participants are given a course on relaxation techniques (e.g. deep breathing exercises, positive visualization training, etc.). After the course, the participants are given another 3 hours to read and study a chapter in a textbook and then they are given another 10 question quiz on the material (half of the participants received one chapter/quiz first and the other half received the other chapter/quiz first). The participants were encouraged to utilize the relaxation techniques they had learned in the course while taking the quiz. Use the data collected in the following table to determine if there is sufficient evidence at the 1% level of significance using a standard two-tailed test that relaxation techniques improve exam performance for those suffering from extreme test anxiety.
