Answer 2

The middle 50% of the scores were 20 points apart.

Explanation:

We know that a interquartile range is the difference between the upper quartile (i.e.
`Q_3`) and lower quartile i.e.
`Q_1`.

It describes the middle 50% of the value when the data points are ordered from least to highest.

Hence, here the interquartile range is given to be 20 points.

This means that the middle 50% of the scores were 20 points apart.
