Asked by Michelle
A random sample obtained from a population has a mean of µ=100 and a standard deviation of ó = 20. The error between the sample mean and the population mean for a sample of n = 16 is 5 points and the error between a sample men and population mean for a sample of n = 100 is 2 points. Explain the difference in the standard error for the two samples.

The measure of variability for distribution of means is SEm.
SEm = SD/√n
As n increases, the SEm decreases.
SEm = SD/√n
As n increases, the SEm decreases.
