Question
SE=σn S E=\frac{\sigma}{\sqrt{n}} \newlineThe given equation relates the standard error, SE S E , of a sample mean to the population standard deviation, σ \sigma , and the size of the sample, n n . Which of the following equations correctly gives the size of the sample in terms of the standard error and the population standard deviation?\newlineChoose 11 answer:\newline(A) n=(σSE)2 n=\left(\frac{\sigma}{S E}\right)^{2} \newline(B) n=σ2SE n=\frac{\sigma^{2}}{S E} \newline(C) n=(σSE) n=\sqrt{\left(\frac{\sigma}{S E}\right)} \newline(D) n=σSE n=\frac{\sqrt{\sigma}}{S E}
