I need the answer and the explanation, please.

Answer 1

Answer:

A.one sample z-confidence interval for the population proportion

Step-by-step explanation:

-A confidence interval is a range of values in which the true population mean is believed to lie.

-Given just one sample, the one sample z-confidence interval for the population proportion is appropriate and is defined as:

$CI=\dot p\pmz_{\alpha/2}\sqrt{\frac{\dot p(1-\dot p)}{n}$
