Suppose a market analyst wants to determine the difference in the average price of a gallon ofwhole milk in Seattle and Atlanta. To do so, he takes a telephone survey of 21 randomly selectedconsumers in Seattle who have purchased a gallon of milk and asks how much they paid for it.The analyst undertakes a similar survey in Atlanta with 18 respondents.
