Question

I’m not sure how to figure out this question. I’ve tried asking friends but none of us know how to convert a graph into a list of numbers

Answer 1

Explanation

We are given the following box plot:

We are required to determine the interquartile range from the box plot given.

We know that the interpretation of box plot is as follows:

Therefore, we have:

$\begin{gathered} min=50 \\ Q_1=53 \\ median=71 \\ Q_3=84 \\ max=96 \end{gathered}$

We also know that the formula for interquartile range is given as:

$interquartile\text{ }range=Q_3-Q_1$$\therefore interquartile\text{ }range=84-53=31$

Hence, the answer is 31.

The last option is correct.
