A. Approximately normal because \( n \leq 0.05 \mathrm{~N} \) and \( n p(1-p)<10 \). Not normal because \( n \leq 0.05 \mathrm{~N} \) and \( n p(1-p) \geq 10 \).
D. Not normal because \( n \leq 0.05 \mathrm{~N} \) and \( n p(1-p)<10 \).
Determine the mean of the sampling distribution of \( \hat{p} \).
\( \mu_{p}=0.6 \) (Round to one decimal place as needed.)
Determine the standard deviation of the sampling distribution of \( \hat{p} \).
\( \sigma_{\hat{p}}=\square \) (Round to three decimal places as needed.)
