A researcher predicts that scores in treatment A will be higher than scores in treatment B. If the mean for the n = 10 participants in treatment A is 4 points higher than the mean for the n = 10 participants in treatment B and the data produce t = 1.985, which decision should be made? O a. reject Ho if a = 0.05 and if a = 0.01 O b. fail to reject Ho if a = 0.05 but reject Ho if a = 0.01 O c. reject Ho if a = 0.05 but fail to reject Ho if a = 0.01 O d. fail to reject Ho if a = 0.05 and if a = 0.01
