Answer
$\hat{p}$ = 0.423
$\hat{q}$ = 0.577
Work Step by Step
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 = 11,605, $x$ = 4912
Therefore, $\hat{p}$ = $\frac{x}{n}$ = $\frac{4912}{11,605}$ = 0.4232 $\approx$ 0.423
ii) $\hat{q}$ = 1 - $\hat{p}$
$\hat{q}$ = 1 - 0.423
$\hat{q}$ = 0.577
