To calculate the interquartile range (IQR), we subtract the first quartile (Q1) from the third quartile (Q3).
From the box plot you provided:
- Q1 = 20
- Q3 = 30
The IQR is calculated as follows:
IQR = Q3 - Q1 = 30 - 20 = 10
Therefore, the interquartile range is **10 books**.
The correct answer is **C. 10 books**.
