Answer
Explanation:
Step1: Identify quartiles
In a five - number summary, the first quartile ($Q_1$) is the second value, and the third quartile ($Q_3$) is the fourth value. Here, $Q_1 = 48$ and $Q_3=64$.
Step2: Calculate inter - quartile range
The inter - quartile range (IQR) is given by $IQR = Q_3 - Q_1$. So, $IQR=64 - 48$. $IQR = 16$
Answer:
16
