Reference no: EM1393012

A random sample obtained from a population has a mean of µ=100 and a standard deviation of σ = 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 mean and population mean for a sample of n = 100 is 2 points. Explain the difference in the standard error for the two samples.
