Step 2: Concept

A histogram is a graphing tool that is often used. It's used to summarise data that's either discrete or continuous and measured on an interval scale.

Step 3: Calculation

To the right of $30$determine the heights of the bars: $5,1,1$

$\frac{7}{50}=0.14=14\%$

As a result, at least $30\%$ of women aged $15$ and up in seven out of fifty states have never married. As a result, the correct answer is (d) $14\%$
