Find the minimum sample size you should use to assure that your estimate of pÌ will be within the required margin of error aroun

Jlenok [28]

Answer:

The minimum sample size required is 97.

Step-by-step explanation:

The (1 - α)% confidence interval for the population proportion is:

$CI=\hat p\pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}$

The margin of error for this confidence interval is:

$MOE=z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}$

The information provided is:

$\hat p=0.20\\MOE=0.08\\\text{Confidence level}=95\%$

The critical value of z for 95% confidence level is, z = 1.96.

Compute the minimum sample size required as follows:

$MOE=z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}$

$n=[\frac{z_{\alpha/2}\cdot\sqrt{\hat p(1-\hat p)}}{MOE}]^{2}\\\\=[\frac{1.96\times \sqrt{0.20(1-0.20)}}{0.08}]^{2}\\\\=96.04\\\\\approx 97$

Thus, the minimum sample size required is 97.

Whats the answer to 3,000(6-2) + 3,000

yuradex [85]

The answer is 15000

$3000 \times ( 6 - 2) = 12000 + 3000 = 15000$
3000*6=1800
3000*-2=-6000
18000-6000=12000
12000+3000=15000
