Or another way of thinking about it, if that area is 5%, this whole area right over here is 95%. And once again, this is a one-tailed test, because we only care about values greater than this. Z values greater than that will make us reject the null hypothesis. And to figure out this critical z value, we can literally just go to a z table. And we say, OK, the probability of getting a z value less than that is 95%. And that's exactly the number that this gives us, the cumulative probability of getting a value less than that. And so if we just scan this, we're looking for 95%.
