$\hat{p}$ = 0.830 $\hat{q}$ = 0.170
i) The point estimate of the population proportion is given by $\hat{p}$ = $\frac{x}{n}$. Here, $x$ represents the # of successes and n represents the sample size. n = 2939, $x$ = 2439 Therefore, $\hat{p}$ = $\frac{x}{n}$ = $\frac{2439}{2939}$ = 0.8298 $\approx$ 0.830 ii) $\hat{q}$ = 1 - $\hat{p}$ $\hat{q}$ = 1 - 0.830 $\hat{q}$ = 0.170
