Tests for adverse reactions to a new drug yielded the results given in the table.Use a 10% level of significance. $$\begin{array} { r | c c }
& \text { Drug } & \text { Placebo } \
\hline \text { Headaches } & 11 & 7 \
\text { No headaches } & 73 & 91
\end{array}$$ $x ^ { 2 }$ = 1.798; P-value = 0.1799 The data will be analyzed to determine if there is sufficient evidence to conclude that an association exists between the treatment (drug or placebo)and the reaction (whether or not headaches were experienced).
A)Do not reject the null hypothesis.Report that there is insufficient evidence to conclude that the distribution of headaches is uniform for the drug and placebo.
B)Reject the null hypothesis.Report that there is sufficient evidence to conclude that treatment and reaction are dependent.
C)Reject the null hypothesis.Report that there is insufficient evidence to conclude that treatment and reaction are dependent.
D)Do not reject the null hypothesis.Report that there is sufficient evidence to conclude that treatment and reaction are dependent.
E)Do not reject the null hypothesis.Report that there is insufficient evidence to conclude that treatment and reaction are dependent.

Given the P-value of 0.1799 is greater than the significance level of 0.10, there is insufficient evidence to reject the null hypothesis, indicating no significant association between treatment and reaction.
