We're decreasing the level of significance, which would lower the probability of making a type one error, but this would decrease the power. It actually would increase, it actually would increase the probability of making a type two, a type two error. And so which of these choices are consistent with that? Well, choice A says that both the type two error and the power would decrease. Well, those don't, these two things don't move together. If one increases, the other decreases. So we rule that one out.
