And if we want that in terms of standard deviations, we just divide by our standard deviation. We divide by 1.34. I'll take out the calculator for this. So we have 2.2 divided by 1.34 is equal to 1.64. So this is equal to 1.64. And that's choice C. So this was actually very straightforward. We just had to see how far away we are from the mean if we get a score of 5, which hopefully you will get if you're taking the AP Statistics exam after watching these videos.
