Answer:
[tex]IQR = 15[/tex]
Step-by-step explanation:
Given
I will answer this question with the attached plot
Required
The interquartile range (IQR)
This is calculated using:
[tex]IQR = Q_3 - Q_1[/tex]
On the second attachment, I identified Q1 and Q3 on the plot.
So, we have:
[tex]Q_3 = 40[/tex]
[tex]Q_1 = 25[/tex]
[tex]IQR = Q_3 - Q_1[/tex]
[tex]IQR = 40 - 25[/tex]
[tex]IQR = 15[/tex]
