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
