A random sample of 600 voters in a particular city found 102 voters who voted yes on proposition 200. find a 95% confidence inte

nexus9112 [7]

N = 600, the sample size

Because 102 voters said 'Yes' to the proposition, the sample proportion is
$\hat{p} = \frac{102}{600} =0.17 \\
1 - \hat{p} = 1-0.17 = 0.83$

The standard error is
$SE_{p} = \sqrt{ \frac{\hat{p}(1-\hat{p})}{n} } = \sqrt{ \frac{(0.17)(0.83)}{600} } = 0.0153$

The confidence interval is
$\hat{p} \pm z^{*} SE_{p}$

From tables, z* = 1.96 at the 95% confidence level.
Therefore the confidence interval is
$0.17 \pm 1.96(0.0153) = (0.14, 0.20)$

Answer: (0.14, 0.20)
