based on data from who, a representative sample of 11-year-old males could consist of the following 15 values.
15.7,16.0,13.9,15.3,18.6,14.8,17.7, 16.6,18.1,19.2,16.3,17.3,16.9,25.6, 20.4
using this data, calculate the 85th percentile. give your answer precise to one decimal place.
85th percentile =
