Answer: 323

Step-by-step explanation:

The formula to calculate the sample size for proportion is given by :_

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

Given : Significance level : $\alpha: 1-0.95=0.095$

Critical value : $z_{\alpha/2}=1.96$

Margin of error : $E=0.05$

The proportion of successes : $p=0.70$

Now, the required sample size will be :-

$n=0.70(0.30)(\dfrac{(1.96)}{0.05})^2=322.6944\approx323$

Hence, the minimum required sample size = 323

Percent error = |actual error - expected error/ expected error| * 100%

(|75-95|)/95 = 0.21

0.21 * 100% = 21% error
