Let's put more details in the given question to better understand the problem:

Let's now answer the questions:

A. What is the median score of class A?

Based on the given box plot, the median score of Class A is 73.

The answer is 73.

B. What is the interquartile range of class B?

For us to get the interquartile range, we will be using the following formula:


\text{ Interquartile range = Q}_3\text{ - Q}_1

In the given box plot for Class B, the following are observed:

Q3 = 87

Q1 = 79

Therefore, the interquartile range will be:


\text{ Interquartile range = 87 - 79 = 8}

The interquartile range of Class B is 8.

The answer is 8.
