The regional manager of a chain of department stores created the following stem-and-leaf plot showing the number of pairs of glasses at each of the stores: \left| \quad \begin{matrix} 0 \vphantom{\Large{0}} \\ 1 \vphantom{\Large{0}} \\ 2 \vphantom{\Large{0}} \\ 3 \vphantom{\Large{0}} \\ 4 \vphantom{\Large{0}} \\ \end{matrix} \quad \right| \quad \begin{matrix} 9& \vphantom{\Large{0}} \\ 3&6&6&8& \vphantom{\Large{0}} \\ 1&2&3&5&6&9& ; \vphantom{\Large{0}} \\ 0& \vphantom{\Large{0}} \\ 1&2&3&3&5&7& ; \vphantom{\Large{0}} \\ \end{matrix}
