Let's say it is right over here, that if you are in that, if you are at that score, you have reached the minimum threshold to get additional screening. You are in the top 30%. So that means that this area right over here is going to be 30%, or 0.3. So what we can do, we can use a z-table to say for what z-score is 70% of the distribution less than that, and then we can take that z-score and use the mean and the standard deviation to come up with an actual value. In previous examples, we started with a z-score and we're looking for the percentage. This time, we're looking for the percentage. We want it to be at least 70% and then come up with the corresponding z-score.
