1. Assume that you are working with the results of a research based on 25 participants. The mean difference (Dbar) is 9.72, with an estimate of the standard error of the mean difference sDbar = 6.33. Set your level of significance at .05.
2. Consider a research project involving two independent samples: Sample A and Sample B:
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 sxbar1-xbar2 = 2.15. Set your level of significance at .05.
