The 'Blue Check Mark' means that this solution was answered by an expert.

Arrange the data in order from lowest to highest.

9   12   15   16   18   19   20   22   24   25

Then substitute into the formula.

Percentile = $\frac{(\text{number of values below }X) + 0.5}{\text{total number of values}}$ · 100

Since there are 3 numbers below the value of 16, the solution is

Percentile = $\frac{3 + 0.5}{10}$ · 100 = 35th percentile

Hence, the value of 16 is higher than 35% of the data values.
