Questions 1 through 4 refer to the following research scenario and data: You are interested in determining whether biofeedback has an impact on headaches. You design an experiment in which 8 participants with tension headaches keep daily logs of the number of headaches they experience during a 2-week baseline period. Then, you train them to use a biofeedback technique. After 6 weeks of training, during which the participants have become successful using the biofeedback technique, they again keep a 2-week log of the number of headaches experiences. The following are the numbers of headaches recorded during each 2-week period: Subject Baseline(pre) After Training(post) Using SPSS where appropriate, test if biofeedback had a significant effect on the number of headaches experienced. Test at an a = .05 2-tail. 1. Identify the null (Ho) and alternative (H1) hypotheses. Ho: Biofeedback does not have an impact on headaches O Ho: Biofeedback does have an impact on headaches OH1: Biofeedback does not have an impact on headaches O H1: Biofeedback does have an impact on headaches
