Explanation:

The p - th percentile of a data set is the value such that p percent of the data values are less than or equal to that value. The 85th percentile is a data - value such that 85% (or 0.85) of the data lies to the left of it when the data is arranged in ascending order. In the context of the standard normal distribution (using z - scores), we are looking for a data value associated with an area of 0.85 to its left.
