A researcher is examining whether daily exercise influences mood. The researcher assigns n = 27 individuals to exercise for three months and finds an average mood score of M = 23 with SS = 182 in this group. A second group of n = 23 individuals assigned to a control group attains an average mood score of M = 24 with SS = 90. Which of the following is most consistent with the test statistic obtained by a two- tailed independent-measures t test with α = .01?
