The 80th percentile is the test score
such that
where
denotes a random variable for SAT test scores. Converting to a standard normal distribution, you have
where
follows the standard normal distribution. A probability of 0.8 roughly corresponds to a z-score of about

So if
, the 80th percentile in terms of
would be
Rounding to the nearest ten suggests you scored 580 on the SAT.
