Short Answer

TABLE 12-8
The director of transportation of a large company is interested in the usage of the company's van pool program. She surveyed 129 of her employees on the usage of the program before and after a campaign to convince her employees to use the service and obtained the following:
$\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$ $\quad$$\text { Before }$
$\begin{array} { l | l | c | l | l } \hline & & \text { Use } & \text { Do Not Use } & \text { Total } \\\hline \text { After } & \text { Use } & 27 & 44 & 71 \\\hline & \text { Do Not Use } & 33 & 25 & 58 \\\hline & \text { Total } & 60 & 69 & 129\end{array}$ She will use this information to perform test using a level of significance of 0.05.
-Referring to Table 12-8, the director now wants to know if the proportion of employees who use the service before the campaign and the proportion of employees who use the service after the campaign are the same. What is the p-value of the test statistic using a 5% level of significance?
