You have seen that the larger the sample size, the smaller the sampling error tends to be in estimating a population mean by a sample mean. This fact is reflected mathematically by the formula for the standard deviation of the sample mean: σx¯ = σ/√n. For a fixed sample size, explain what this formula implies about the relationship between the population standard deviation and sampling error.
