The results are listed in the table below,and a graphical display of the conditional distributions of sex among the three categories of politics is given. $$\begin{array}{l}\begin{array} { | l | c c c | c | } &\text { Politics }\\\hline \text { sex}& \text { Liberal } & \text { Moderate } & \text { Conservative } & \text { Total } \\\hline \text { Female } & 45 & 49 & 8 & 102 \\ & 64 & 53 & 29 & 146 \\\hline \text { Male } & 64 & 102 & 37 & 248 \\\hline \text { Total } & 109 & 148\end{array}\end{array}$$ The political science instructor states that sex and politics are independent.Is this an accurate statement? Explain.
