You compare the mean to two other groups who did notreceive the relaxation therapy. One group, n=10 received notreatment and averaged 19.7 cigarettes at the end of eight weeks,and the other group, n=10 who was given literature on the negativeeffects of smoking averaged 18.1 cigarettes after eight weeks. Youcalculate the means of all groups using the appropriate hypothesisstatistic. You hypothesize that there will be a difference in themeans after eight weeks. You measure smoking levels after youterminate the therapy to see if there are effects from theindependent variable. The obtained test statistic is 12.396 and a pvalue of 0.000152. You used the alpha level of 0.05.
