Construct a comparative boxplot that makes it possible to compare wireless percent for the three geographical regions.
The box-and-whisker plot has a vertical axis numbered from 25 to 60. The box-and-whisker is also vertical. The boxplot labeled "East" occurs next. The bottom whisker is approximately 40.8, the bottom edge of the box is approximately 43.5, the line inside the box is approximately 47.1, the top edge of the box is approximately 51.5, and the top whisker is approximately 56.2. The boxplot labeled "West" occurs next. The bottom whisker is approximately 38.4, the bottom edge of the box is approximately 41.9, the line inside the box is approximately 48.4, the top edge of the box is approximately 51.15, and the top whisker is approximately 56.1. The boxplot labeled "Middle" occurs next. The bottom whisker is approximately 25.2, the bottom edge of the box is approximately 31.1, the line inside the box is approximately 37.1, the top edge of the box is approximately 45.8, and the top whisker is approximately 49.7.
