Homework Answers
Answer:
We know that the standard error is defined as the population standard deviation divided by the square root of sample size n. When n = 1, then standard error of the mean is equal to the population standard deviation. As we increase the sample size n, then the standard error decreases. The standard error of the mean, σx̄, is always smaller than or equal to the population standard deviation σ.
