Answer 2

Answer:

B. 17 books

Step-by-step explanation:

We have been given a box plot. We are asked to find interquartile range for our given box-plot.

We know that interquartile range is difference of upper quartile and lower quartile.

$IQR=Q_3-Q_1$

We know that first line of box plot represents lower quartile and last line of box represents lower quartile.

$IQR=25-8$

$IQR=17$

Therefore, 17 books is the interquartile range of the number of books read by the students in Mr. Ford's class.
