A researcher is examining whether daily yoga reduces stress. The researcher assigns n = 7 individuals to engage in daily yoga for three months and finds an average stress score of M = 16 with SS = 123 after three months for individuals in this group. A second group of n = 6 individuals assigned to a control group for the three months had a stress score of M = 21 with SS = 141. Which of the following is most consistent with the results of conducting a one-tailed independent-measures t test with α = .05? a. t = -1.83 and fail to reject the null hypothesis b. t = -1.83 and reject the null hypothesis c. t = -1.61 and fail to reject the null hypothesid. s t = -1.61 and reject the null hypothesis
