The speed limit for the entrance is 15 mph. The high school principal argues that speeds up to 20 mph are acceptable, so nothing needs to be done about students speeding into the entrance. However the vice principal thinks that there is a problem that needs to be addressed, probably by issuing speeding tickets. How could the vice principal use this box-and-whisker plot and the principal’s statement that “speeds up to 20 mph are acceptable” to argue her position? Use mathematics in your explanation.
