Answer: 3

Step-by-step explanation:

We know that the interquartile range is known as the range of the middle 50% of the data.

  • Interquartile range is the difference between the third quartile and first quartile.

From the given box plot , the first quartile ( where box starts ) [tex]Q_1= 4[/tex]

The third quartile  ( where box ends ) [tex]Q_3= 7[/tex]

Then, the interquartile range = [tex]Q_3-Q_1= 7-4=3[/tex]

Thus , the range of the middle 50% of the data =3
