the Director of Admissions at a State College

question 51

Short Answer

TABLE 12-10
The director of admissions at a state college is interested in seeing if admissions status (admitted, waiting list, denied admission) at his college is independent of the type of community in which an applicant resides. He takes a sample of recent admissions decisions and forms the following table:
$$\begin{array} { l | l l l | l } & \text { Admitted } & \text { Wait List } & \text { Denied } & \text { Total } \\\hline \text { Urban } & 45 & 21 & 17 & 83 \\\text { Rural } & 33 & 13 & 24 & 70 \\\text { Suburban } & 34 & 12 & 39 & 85 \\\hline \text { Total } & 112 & 46 & 80 & 238\end{array}$$ 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 value of the test statistic is _______.
