Ten women participate in a study. A physical therapist measures the women's waistlines before and 8 weeks after a rigorous exercise program begins. Test whether the program decreased the median waistline at the a= 0.05 level of significance. Before (inches) After (inches) 24 20 21.75 19.75 22.25 25.75 17.75 35.5 19.5 21.25 22.75 24.5 19.75 34 36.25 35.5 53.5 30.5 51.25 30.5 What is the conclusion of the hypothesis test? O A. Since the test statistic is greater than the critical value, there is not sufficient evidence to indicate that the exercise program is effective in reducing wasteline. O B. Since the test statistic is less than the critical value, there is not sufficient evidence to indicate that the exercise program is effective in reducing wasteline. OC. Since the test statistic is greater than the critical value, there is sufficient evidence to indicate that the exercise program is effective in reducing wasteline. D. Since the test statistic is less than the critical value, there is sufficient evidence to indicate that the exercise program is effective in reducing wasteline
