A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtain

Ivanshal [37]

Answer:a-396

b-420

Step-by-step explanation:

$\alpha$ =0.1

Margin of Error=0.04

Level of significance is z $\left ( 0.1\right )=1.64$

Previous estimate $\left ( p\right ) =0.38$

sample size is given by:

n= $\left (\frac{Z_{\frac{\alpha }{2}}}{E}\right )p\left ( 1-p\right )$

n= $\frac{1.64}{0.04}^{2}0.38\left ( 1-0.38\right )=396.0436\approx 396$

$\left ( b\right )$ Does not use prior estimate

Assume

$\alpha$ =0.1

Margin of Error=0.04

Level of significance is z $\left ( 0.1\right )=1.64$

Population proportion $\left ( p\right )$ =0.5

n= $\left (\frac{Z_{\frac{\alpha }{2}}}{E}\right )p\left ( 1-p\right )$

n= $\frac{1.64}{0.04}^{2}0.5\left ( 1-0.5\right )$

n=420.25 $\approx 420$
