14.31 Power against a different alternative.
Refer to the previous exercise. Suppose we increase to 3.9. For each of the choices of in the previous example, would the power be larger or smaller under this new set of alternative means? Explain your answer.
14.31
The power would be larger. For larger differences between alternative means, gets bigger, increasing our power to see these differences.
