P(black socks): 24/42 or 12/21
P(black socks without replacing): 23/41. As a result, the probability of randomly picking 2 black socks, without replacement, from the basket is 12/21×23/41=276/861 or 32%. Hope it help!

Anvisha [2.4K]

Answer: \mu_{\hat{p}}=0.14 and \sigma_{\hat{p}}=0.0347

Step-by-step explanation:

In sampling distribution of \hat{p}.

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

\mu_{\hat{p}}=p

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

Let p be the population proportion of unmarried couples in the United States are mixed racially or ethnically.

As per given , we have

n = 100

p= 14% =0.14

Then, the mean and standard deviation of the sampling distribution of p will be :

\mu_{\hat{p}}=0.14

\sigma_{\hat{p}}=\sqrt{\dfrac{0.14(1-0.14)}{100}}

\sigma_{\hat{p}}=\sqrt{\dfrac{0.14(0.86)}{100}}

\sigma_{\hat{p}}=\sqrt{\dfrac{0.1204}{100}}

\sigma_{\hat{p}}=\sqrt{0.001204}

\sigma_{\hat{p}}=0.0346987031458\approx0.0347

Hence, the required answer : \mu_{\hat{p}}=0.14 and \sigma_{\hat{p}}=0.0347
