QuestionHere are the hottest recorded temperatures (in ${ }^{\circ} \mathrm{F}$ ) for each of sixteen cities throughout North America. \begin{tabular}{|c|c|c|c|c|c|c|c|} \hline \multicolumn{7}{|c|}{ Temperatures } \\ $\left(\right.$ in $\left.^{\circ} \mathrm{F}\right)$ \end{tabular}
Send data to calculator (a) Complete the grouped frequency distribution for the data. (Note that the class width is 4. ) \begin{tabular}{|cc|} \hline \begin{tabular}{c} Temperatures \\ (in ${ }^{\circ} \mathrm{F}$ ) \end{tabular} & \begin{tabular}{c} Frequency \end{tabular} \\ \hline 92.5 to 96.5 & $\square$ \\ 96.5 to 100.5 & $\square$ \\ 100.5 to 104.5 & $\square$ \\ 104.5 to 108.5 & $\square$ \\ 108.5 to 112.5 & $\square$ \\ \hline \end{tabular} (b) Using the classes from part (a), draw the frequency polygon for the data. Note that you can add or remove classes from the figure. Label each class with its midpoint.
