Answer 1

`IQR = 15`

Explanation:

Given

I will answer this question with the attached plot

Required

The interquartile range (IQR)

This is calculated using:

`IQR = Q_3 - Q_1`

On the second attachment, I identified Q1 and Q3 on the plot.

So, we have:

`Q_3 = 40`

`Q_1 = 25`

`IQR = Q_3 - Q_1`

`IQR = 40 - 25`

`IQR = 15`
