Suppose that cars arrive at the Burger King’s drive-through at the rate of 20 cars every hour between noon and 1:00 PM. A random sample of 40 one-hour time periods between noon and 1:00 PM is selected and has a mean of 22.1 cars arriving. Assume that µ = 20 and that σ = √20 for the population of cars arriving at Burger King. What is the probability that a simple random sample of 40 one-hour time periods results in a mean of at least 22.1 cars?
