Describe the sampling distribution of p(hat). Assume the size of the population is 30,000.

Naya [18.7K]

Answer:

a) $\mathbf{\mu_ \hat p = 0.6}$

b) $\mathbf{\sigma_p =0.01732}$

Step-by-step explanation:

Given that:

population mean $\mu$ = 30,000

sample size n = 800

population proportion p = 0.6

The mean of the the sampling distribution is equal to the population proportion.

$\mu_ \hat p = p$

$\mathbf{\mu_ \hat p = 0.6}$

The standard deviation of the sampling distribution can be estimated by using the formula:

$\sigma_p = \sqrt{\dfrac{p(1-p)}{n}}$

$\sigma_p = \sqrt{\dfrac{0.6(1-0.6)}{800}}$

$\sigma_p = \sqrt{\dfrac{0.6(0.4)}{800}}$

$\sigma_p = \sqrt{\dfrac{0.24}{800}}$

$\sigma_p = \sqrt{3 \times 10^{-4}}$

$\mathbf{\sigma_p =0.01732}$

Scilla [17]

Answer:

The standard error of the mean (SE) is of 0.326lb.

Step-by-step explanation:

The standard error of the mean is given by the following formula:

$SE = \frac{s}{\sqrt{n}}$

In which s is the standard deviation of the sample and n is the size of the sample.

In this problem, we have that:

$s = 4.3, n = 174$

Then

$SE = \frac{s}{\sqrt{n}} = \frac{4.3}{\sqrt{174}} = 0.326$

The standard error of the mean (SE) is of 0.326lb.
