Here is information about possible versions of a planned experiment. Figure the effect size, beta, and power for each. Sketch the null hypothesis distribution and the research distribution to illustrate the level of power predicted in each scenario. Use a = .05 and a 2-tailed test for each. Discuss the difference in power and why this difference occurred.
Study A: Mean = 68, Standard Deviation - 7, Predicted Mean = 76, N = 25
Study B: Mean = 68, Standard Deviation = 7, Predicted Mean = 76, N = 72
