Assume that you plan to use a significance level of $\alpha = 0.05$ to test the claim that $p _ { 1 } = p _ { 2 }$. Use the given sample sizes and numbers of successes to find the pooled estimate $\bar { p }$. Round your answer to the nearest thousandth.
$\begin{array} { l l }
n _ { 1 } = 100 & n _ { 2 } = 100 \
x _ { 1 } = 42 & x _ { 2 } = 45
\end{array}$
A) $0.479$
B) $0.435$
C) $0.305$
D) $0.392$
