Consider a research situation involving two independent samples, Sample A and Sample B. (Assume that you are subtracting the Mean of Sample B from the Mean of Sample A.) Mean of Sample A = 30.45 n = 25 Mean of Sample B = 26.54 n = 27 Estimate of the standard error of the difference of means (s _ _ ) = 2.15. Assume that you’re working at the .05 level of significance.x1−x2

a. Formulate an appropriate null hypothesis.

b. Calculate t statistic.
