$\begin{array} { | l | c | c | c | } \hline& \text { Male } & \text { Female } & \text { Total } \\\hline \text { Bus } & 30 & 34 & \mathbf { 6 4 } \\\hline \text { Ride } & 37 & 45 & \mathbf { 8 2 } \\\hline \text { Personal } & 19 & 23 & \mathbf { 4 2 } \\\hline \text { Total } & \mathbf { 8 6 } & \mathbf { 1 0 2 } & \mathbf { 1 8 8 } \\\hline\end{array}$
