In order to determine the standard error of the mean, we need to know
A) μ and σ.
B) σ and n.
C) M and σ.
D) μ and n.

Question

Quizplus · Accepted Answer

The standard error of the mean (SEM) is calculated using the formula SEM = σ/√n, where σ is the population standard deviation and n is the sample size. Therefore, we need to know both σ and n to determine the SEM. Choice A (μ and σ) only gives us the population mean and standard deviation, but we need the sample size. Choice C (M and σ) only gives us the sample mean, but we also need the sample size. Choice D (μ and n) only gives us the population mean and sample size, but we also need the population standard deviation.
