# An assistant to the mayor, who claims to understand statistics, complains

about your confidence interval calculation. She asserts that the dollar losses from burglaries are not normally distributed, which in turn makes the confidence interval calculations meaningless. Assume that she is correct about the distribution of money loss. Why are the calculations of a confidence interval still appropriate? According to the central limit theorem any distribution is considered normal if n is greater than _. This sample is 500 so the distribution of the sample means will be normal, no matter what the shape of the actual distribution of dollar losses.
