Use a $\chi ^ { 2 }$ test to test the claim that in the given contingency table, the row variable and the column variable are independent. Tests for adverse reactions to a new drug yielded the results given in the table. At the $0.05$ significance level, test the claim that the treatment (drug or placebo) is independent of the reaction (whether or not headaches were experienced).
$\begin{array}{r|cc}
& \text { Drug } & \text { Placebo } \
\hline \text { Headaches } & 11 & 7 \
\text { No headaches } & 73 & 91
\end{array}$
