The Use of the Standard Normal Distribution for Constructing a Confidence

question 54

Short Answer

The use of the standard normal distribution for constructing a confidence interval estimate for the population proportion p requires that: $\begin{array}{|l|l|}\hline A&\text {\( n \hat{p} \) and \( n(1-\hat{p}) \) are both greater than 5 , where \( \hat{p} \) denotes the sample proportion. }\\\hline B&\text {\( n p \) and \( n(1-p) \) are both greater than 5 . }\\\hline C&\text {\( n \hat{p} \) and \( n(p+\hat{p}) \) are both greater than 5 . }\\\hline D&\text {the sample size is greater than 5 . }\\\hline \end{array}$
