44. A researcher is examining whether daily exercise influences mood. The researcher assigns n = 12 individuals to exercise for three months and finds an average mood score of M = 22 with SS = 182 after three months for individuals in this group. A second group of n =7 individuals assigned to a control group for the three months has a mood score of M = 19 with SS = 90. Which of the following is most consistent with the results of conducting a two- tailed Independent-Measures t-test with a = .05? a. t= +2.12 and fail to reject the null hypothesis b. t= +2.12 and reject the null hypothesis c. t= +1.58 and fail to reject the null hypothesis d. t= +1.58 and reject the null hypothesis
