Well, we're not going to reject the null hypothesis if we get samples in, if we get a sample here or a sample here or a sample here. A sample where if you assume the null hypothesis is true, the probability isn't that unlikely. And so the probability of making a type two error when we should reject the null hypothesis but we don't is actually this area right over here. And the power, the probability of rejecting the null hypothesis given that it's false, so given that it's false would be this red distribution, that would be the rest of this area right over here. So how can we increase the power? Well, one way is to increase our alpha, increase our significance level. If we increase our significance level, say from that, remember the significance level is an area.
