Each Individual in a Random Sample of High School and College

Each individual in a random sample of high school and college students was cross-classified with respect to both political views and marijuana usage, resulting in the data displayed in the accompanying two-way table. Does the data support the hypothesis that political views and marijuana usage level are independent within the population? Test the appropriate hypotheses using level of significance .01. $\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$$\quad$ $\quad$$\text { Usage Level }$
$$\begin{array}{l}\begin{array} { l | c c c } \hline \begin{array} { l } \text { Political } \\\text { Views }\end{array} & \text { Never } & \text { Rarely } & \text { Frequently } \\\hline \text { Liberal } & 480 & 180 & 120 \\\text { Conservative } & 215 & 50 & 15 \\\hline \text { Other } & 170 & 45 & 85 \\\hline\end{array}\end{array}$$
