Question

Consider testing the hypotheses $H_0: p_1 = p_2$ versus $H_a: p_1 \neq p_2$ given that $x_1 = 107$, $n_1 = 477$, $x_2 = 84$, $n_2 = 336$, and the level of confidence $\alpha = 0.05$. A. Find point estimates of the population proportions for each sample. $\hat{p}_1 = $ $\hat{p}_2 = $ Round to 4 decimal places B. Find the test statistic. $z = $ Round to 4 decimal places C. Find the $P$-value. $P\text{-value} = $ Round to 4 decimal places

          Consider testing the hypotheses
