If All Possible Samples of Size N Are Drawn from an Infinite

Short Answer

If all possible samples of size n are drawn from an infinite population with a mean of 15 and a standard deviation of 5, then the standard error of the sample mean equals 1.0 only for samples of size: $\begin{array}{|l|l|}\hline \text { A. } & 5 . \\\hline \text { B. } & 15 . \\\hline \text { C. } & 25 . \\\hline \text { D. } & 75 . \\\hline\end{array}$
