Percentile[<List of Numbers>, <Percent>]
Let P equal the given Percent.
Returns the value that cuts off the first P percent of the number list when the list is sorted in ascending order. Percent must be a number in the interval 0 < P ≤ 1.
Note: The commands Quartile and Percentile use different rules and do not always return matching results. For example,
Q1[ {1,2,3,4} ] = 1.5
Percentile[ {1,2,3,4}, .25 ] = 1.25
