"A tire manufacturer designed a new tread pattern for its all-weather tires. Repeated tests were conducted on cars of approximately the same weight traveling at $60$ $mph$. The tests showed that the new tread pattern enables the cars to stop completely in an average distance of $125$ $ft$.
For every sample of five cars tested, the average of the maximum and minimum stopping distances is calculated. (This is called the midrange.) Numerous samples give sample midranges graphed in the dotplot below:
