MakcuM [25]

Answer: $\mu_{\hat{p}}=0.67$

$\sigma_{\hat{p}}=0.029$

Step-by-step explanation:

The mean and standard deviation of the sampling distribution of the sample proportions is given by :-

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

$\sigma_{\hat{p}}=\sqrt{\dfrac{p(1-p)}{n}}$ , where n is the sample size and p is the population proportion.

Given : p= 0.67 and n= 256

Then, the mean and standard deviation of the sampling distribution of the sample proportions is given by :-

$\mu_{\hat{p}}=0.67$

$\sigma_{\hat{p}}=\sqrt{\dfrac{0.67(1-0.67)}{256}}\\\\=0.0293882948638\approx0.029$
