A large pizza chain tracks how many pizzas each customer buys per order. The number of pizzas customers buy in any given order has a mean of 2.52.52, point, 5 pizzas and a standard deviation of 1.51.51, point, 5 pizzas.

Suppose that we take random samples of 777 orders from this population and calculate \bar{x}
x

x, with, \bar, on top as the sample mean number of pizzas purchased per order. We can assume that the orders in each sample are independent.
