See Explanation

Step-by-step explanation:

The question is incomplete as the box and whisker plots for the Pre-test A and the Pre-test B are not given. I will answer this question with the attached image.

The attached image contains three plots.

The first plot shows the description of how to read the box and whisker plot.

From the description image, the following represents the summary of the plot

The green line: Minimum

The blue line: Lower Quartile (Q1)

The red line: Median (Q2)

The yellow line: Upper Quartile (Q3)

The last green line: Maximum

Using the above descriptions to read the pre-test A and pre-test B plots.

The lower quartile of pre-test A is:

The lower quartile of pre-test B is:

The difference (D) is calculated as:

The difference is 5
