Consider the two plots showing the null distribution (dashed), and two tails (dashed vertical lines) each with 2.5% of the area of the null, as well as two different alternate distributions (solid lines). Which one of the following statements is correct? probability density 0.4 0.3 0.2 0.1 0.0 0 2 4 8 10 probability density 0.4 0.3 0.2 0.1 0.0 0 2 4 6 8 10 The one on the left has more statistical power because it rejects the null more often when the null is correct The one on the left has more statistical power because it rejects the null more often when the alternate is correct The one on the right has more statistical power because it rejects the null more often when the null is correct Both have about the same power because the rejection area of the null is the same The one on the right has more statistical power because it rejects the null more often when the alternate is correct
