Short Answer

TABLE 12-7
The director of transportation of a large company is interested in the usage of her van pool. She considers her routes to be divided into local and non-local. She is particularly interested in learning if there is a difference in the proportion of males and females who use the local routes. She takes a sample of a day's riders and finds the following:
$$\begin{array} { l | l l | l } & \text { Male } & \text { Female } & \text { Total } \\\hline \text { Local } & 27 & 44 & 71 \\\text { Non- Local } & 33 & 25 & 58 \\\hline \text { Total } & 60 & 69 & 129\end{array}$$ She will use this information to perform a chi-square hypothesis test using a level of significance of 0.05.
-Referring to Table 12-7, the overall or average proportion of local riders is ______.
