Final answer:
To find the median of a box-and-whisker plot, locate the line inside the box.
Step-by-step explanation:
To find the median of a set of data represented in a box-and-whisker plot, you need to locate the box in the plot. The median is the value represented by the line inside the box. In this case, the box-and-whisker plot for the amount of recyclable material collected is not provided, so I cannot determine the median.
