In Selecting the Sample Size to Estimate the Population Proportion $\hat { p }$

question 113

Short Answer

In selecting the sample size to estimate the population proportion p, if we have no knowledge of even the approximate values of the sample proportion $\hat { p }$ , we: $\begin{array}{|l|l|}\hline A&\text {take another sample and estimate \( p \). }\\\hline B&\text {take two more samples and find the average of their \( \hat{p} \) values. }\\\hline C&\text {let \( \hat{p}=0.50 \). }\\\hline D&\text {let \( \hat{p}=0.95 \). }\\\hline \end{array}$
