1. You are interested in assessing the effectiveness of a domestic violence counseling program designed to decrease the number of domestic abuse incidents among convicted abusers. The case files of ten offenders are randomly selected from the population of convicted abusers. The number of abuse incidents (verbal or physical) six reported six months before the implementation of the counseling program and six months following the completion of the program are reported below. Using a .01 level of significance, test the hypothesis that the number of abuse incidents was greater before participation in the counseling program.
