A prior study estimated as 34%. The analysts would like to conduct a second study on the same topic with a margin of error, E, o

Volgvan

The minimum sample size required for a test with a confidence interval of $100(1 - \alpha )%$ with a z-score of $z_{ \alpha /2}$ and margin of error of E and a population proportion of p is given by:

$n= \frac{p(1-p)z_{ \alpha /2}^2 \alpha }{E^2}$

Given p = 34% = 0.34, E = 0.027, $z_{ \alpha /2}=1.645$

Therefore,

$n= \frac{0.34(1-0.34)(1.645)^2}{0.027^2} \\ \\ = \frac{0.34(0.66)(2.706025)}{0.000729} = \frac{0.60723201}{0.000729} \\ \\ =832.97=833$
