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. And then you divide by the standard deviation to say how many standard deviations away from the mean is the score of 5, it's 1.64. I think the only tricky thing here might have been you might have been tempted to pick choice E, which says a z-score cannot be calculated because the distribution is not normal. And I think the reason why you might have had that temptation is because we've been using z-scores within the context of a normal distribution.
