3. A researcher would like to determine if relaxation training will reduce the number of headaches for chronic headache sufferers. For a week prior to training, each participant records the number of headaches suffered. Participants then receive relaxation training and for the week following training the number of headaches is again measured. The number of headaches before and after the training follow: Participant: 2 3 4 5 6 7 8 After: 5 16 7 6 10 14 Before: 10 20 10 12 8 10 13 Is there a reliable difference between the number of headaches before and after the training? Use a = .05, and perform a complete hypothesis test, by hand, including a journal style summary statement (Note: If you choose to report each sample mean in your APA summary, the sample means are NOT polite). Repeat the test using SPSS
