The following frequency distribution shows the average number of pupils per teacher in the 50 states of the United States. Find the variance and standard deviation for the data. $\begin{array}{ccc}{\frac{\text { Class limits }}{9-11}} & {\text { Frequency }} \\ \hline 9-11 & {2} \\ {12-14} & {20} \\ {15-17} & {20} \\ {18-20} & {18} \\ {18-20} & {7} \\ {21-23} & {2} \\ {24-26} & {\frac{1}{50}}\end{array}$
