Answer:

The interquartile range of this data is:

8

Explanation:

From the box plot given to us we see that:

Minimum value of the set is: 18

The first quartile or the lower quartile of the set i.e.
Q_1=25

The middle quartile or the median of the set i.e.
Q_2=28

The upper quartile or third quartile i.e.
Q_3=33

Maximum value of the set is: 42

Hence, the interquartile range of the data is:


IQR=Q_3-Q_1\\\\\\IQR=33-25\\\\IQR=8

Hence, the interquartile range is: 8
