Which data set has the greatest mean?<br/><br/>$\begin{tabular}{|c|c|} \hline \begin{tabular}{c} \textbf{Value} \\ \end{tabular} & <br/>\begin{tabular}{c} \textbf{Frequency} \\ \end{tabular} \\ \hline<br/>70 & 4 \\ \hline<br/>80 & 5 \\ \hline<br/>90 & 6 \\ \hline<br/>100 & 7 \\ \hline \begin{tabular}{c} \textbf{Value} \\ \end{tabular} & <br/>\begin{tabular}{c} \textbf{Frequency} \\ \end{tabular} \\ \hline<br/>70 & 6 \\ \hline<br/>80 & 6 \\ \hline<br/>90 & 6 \\ \hline<br/>100 & 6 \\ \hline \begin{tabular}{c} \textbf{Value} \\ \end{tabular} & <br/>\begin{tabular}{c} \textbf{Frequency} \\ \end{tabular} \\ \hline<br/>70 & 7 \\ \hline<br/>80 & 6 \\ \hline<br/>90 & 6 \\ \hline<br/>100 & 7 \\ \hline \begin{tabular}{c} \textbf{Value} \\ \end{tabular} & <br/>\begin{tabular}{c} \textbf{Frequency} \\ \end{tabular} \\ \hline<br/>70 & 8 \\ \hline<br/>80 & 5 \\ \hline<br/>90 & 5 \\ \hline<br/>100 & 8 \\ \hline \end{tabular}$
One method of calculating the approximate age, in years, of a tree of a particular species is to multiply the diameter of the tree, in inches, by a constant called the growth factor for that species. The table above gives the growth factors for eight species of trees. If a white birch tree and a pin oak tree each now have a diameter of 1 foot, which of the following will be closest to the difference, in inches, of their diameters 10 years from now? (1 foot = 12 inches).<br/><br/>####
Employees working for a customer service line at an electric company recorded all the calls last Monday and noted whether the caller asked for repairs and whether the caller asked about a bill.
