Answer
Explanation:
Step1: Recall percentile - rank formula
The formula for the percentile - rank of a value $x$ in a data - set is $PR=\frac{c}{n}\times100$, where $c$ is the number of values less than or equal to $x$ and $n$ is the total number of values in the data - set.
Step2: Identify $c$ and $n$ for the value 5
The data - set is $5,10,19,22,30,32$. The total number of values $n = 6$. The number of values less than or equal to 5 is $c = 1$.
Step3: Calculate the percentile - rank
Using the formula $PR=\frac{c}{n}\times100$, we substitute $c = 1$ and $n = 6$. So, $PR=\frac{1}{6}\times100\approx17$.
