Answer

Explanation:

Step1: Calculate index

First, use the formula $i = p\times n$, where $p = 0.33$ (33rd percentile as a decimal) and $n=6$ (number of data - points). So, $i=0.33\times6 = 1.98$.

Step2: Determine the position

Since $i$ is not an integer, we round up to the next whole - number. Rounding 1.98 gives 2.

Step3: Find the value

The second value in the ordered data set ${5,12,15,16,20,21}$ is 12.

Answer:

12
