How does each of the following affect the power of a planned study? (a) a larger predicted difference between the means of the populations (b) a larger population standard deviation (c) a larger sample size (d) using a more extreme significance level (for example, 0.01 instead of 0.05) (e) using a two-tailed test instead of a one-tailed test

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c

The answer would be a
