Sample proportion
<u><em>Step(ii)</em></u>
The 95% confidence interval estimate of the proportion of people who say that they voted
![(p^{-} - Z_{0.05} \sqrt{\frac{p(1-p)}{n} } , p^{-} + Z_{0.05} \sqrt{\frac{p(1-p)}{n} } )](https://tex.z-dn.net/?f=%28p%5E%7B-%7D%20-%20Z_%7B0.05%7D%20%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%20%7D%20%2C%20p%5E%7B-%7D%20%2B%20Z_%7B0.05%7D%20%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%20%7D%20%29)
![(0.6996 - 1.96\sqrt{\frac{0.6996(1-0.6996)}{1002} } , 0.6996 + 1.96 \sqrt{\frac{0.6996(1-0.6996)}{1002} } )](https://tex.z-dn.net/?f=%280.6996%20-%201.96%5Csqrt%7B%5Cfrac%7B0.6996%281-0.6996%29%7D%7B1002%7D%20%7D%20%2C%200.6996%20%2B%201.96%20%5Csqrt%7B%5Cfrac%7B0.6996%281-0.6996%29%7D%7B1002%7D%20%7D%20%29)
(0.6996 - 1.96 X 0.01448 , 0.6996 + 1.96 X 0.01448)
(0.6996 - 0.02838 , 0.6996 + 0.02838)
(0.67122 , 0.72798)
<u><em>Final answer</em></u>:-
The 95% confidence interval estimate of the proportion of people who say that they voted
(0.67122 , 0.72798)
