This is called the forced expiratory volume in one second, and is abbreviated FEV. Assume the mean FEV, for 10-year-old boys is 2.1 liters andthat the population standard deviation is o =0.3. A random sample of 77 10-year-old boys who live in a community with high levels of ozone pollution are foundto have a sample mean FEV, of 2.03 liters. Can you conclude that the mean FEVi In the high-pollution community is less than 2.1 liters?
