An online retailer studies the amount spent per order. The population distribution is strongly right-skewed because most orders are small but a few are very large. The analyst repeatedly takes random samples of n=100n=100 orders and computes the sample mean amount spent xˉ\bar{x}. She examines the sampling distribution of xˉ\bar{x}. Why is the sampling distribution approximately normal?
