It's 157.7, which just happens to be the exact number they asked for. They're asking for heights, the probability of getting a height higher than that. So they want to know what's the probability that we fall under this area right here. Or essentially, more than two standard deviations from the mean, or above two standard deviations. We can't count this left tail right there. So we can use the empirical rule. If we do our standard deviations to the left, that's one standard deviation, two standard deviations.
