True/False

TABLE 12-10

$$\begin{array} { l | l l l | l } & \text { Admitted } & \text { Wait List } & \text { Denied } & \text { Total } \\\hline \text { Urban } & 45 & 21 & 17 & 83 \\\text { Rural } & 33 & 13 & 24 & 70 \\\text { Suburban } & 34 & 12 & 39 & 85 \\\hline \text { Total } & 112 & 46 & 80 & 238\end{array}$$ He will use this table to do a chi-square test of independence with a level of significance of 0.01.
-Referring to Table 12-10, the null hypothesis will be rejected.
