For the independent-measures t statistic, what is the effect of increasing the sample variances? A)increase the likelihood of rejecting H₀ and increase measures of effect size B)increase the likelihood of rejecting H₀ and decrease measures of effect size C)decrease the likelihood of rejecting H₀ and increase measures of effect size D)decrease the likelihood of rejecting H₀ and decrease measures of effect size
