(Hint: It may help to create a cumulative include a column of cumulative percentages. To ulative percentages, keeping the upper real limits in In the sample data, 9 out of 11 observations are less than or equal to the 85th percentile, and 2 out of 11 observations are greater than or equal to this value.
