The Smarts and the Teasers are two quiz teams that each contain 11 members. Both complete a puzzle and the following table gives the times taken, in minutes, by the members of each team.
For the Teasers, the values of the lower quartile, median and upper quartile are 18, 25 and 37 minutes respectively. On a single diagram draw box-and-whisker plots for the two teams.
