Explanation:

Step1: Recall quartile concept

In a box - and - whisker plot, the box represents the inter - quartile range. The left - hand side of the box is the first quartile ($Q_1$), the line inside the box is the second quartile ($Q_2$ or the median), and the right - hand side of the box is the third quartile ($Q_3$).

Step2: Identify quartile position in box - and - whisker plot

The number of classrooms for Eastward Middle School is 28. Looking at the box - and - whisker plot, values less than the left - hand side of the box are in the first 25% of the data set. Since 28 is less than the value at the left - hand side of the box, it is in the first quartile.

Answer:
