An independent-measures research study examines gender differences in toddlers’ verbal skills. The researchers tested verbal skills of 2-years old girls (i.e., n1 = 12) and 2-years old boys (i.e., n2 = 9). The t-test calculated on the data produced a t = 2.05. Which of the following is the correct decision and conclusion for a two-tails hypothesis test with p < .05? A. Reject the H0 with α = .05; there is no significant gender difference in toddlers’ verbal skills. B. Reject the H0 with α = .05; there is a significant gender difference in toddlers’ verbal skills. C. Fail to reject the H0 with α = .05; there is no significant gender difference in toddlers’ verbal skills. D. Fail to reject the H0 with α = .05; there is a significant gender difference in toddlers’ verbal skills.
