A Sample of 250 Observations Is to Be Selected at Random

Short Answer

A sample of 250 observations is to be selected at random from an infinite population. Given that the population proportion is 0.25, the standard error of the sampling distribution of the sample proportion is: $\begin{array}{|l|l|}\hline\text { A. } & 0.0274 . \\\hline \text { B. } & 0.50 . \\\hline \text { C. } & 0.0316 . \\\hline \text { D. } & 0.0548 . \\\hline\end{array}$
