"a survey reports the percentage of people 18 years of age and older who smoke. suppose that a study designed to collect new dat

zubka84 [21]

Answer: 2017

Step-by-step explanation:

Given : The proportion of people that smoke : p=0.3

Margin of error : E= 0.02

Significance level : $\alpha=1-0.95=0.05$

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

The formula to calculate sample size ( if proportion is known) :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\\Rightarrow\ n=(0.3)(0.7)(\dfrac{(1.96)}{0.02})\\\\\Rightarrow\ n=2016.84approx2017$

Hence, the required minimum sample would be 2017.
