Step-by-step explanation:
Z-score:
In a set with mean and standard deviation
, the z-score of a measure X is given by:

This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
