Easuring lung function: One of the measurements used to determine the health of a person's lungs is the amount of air a person can exhale under force in one second. This is called forced expiratory volume in one second, and is abbreviated FEV1. Assume the mean FEV1 for 10-year-old boys is 2.1 liters and that the population standard deviation is =σ0.4. A random sample of 34 10-year-old boys who live in a community with high levels of ozone pollution are found to have a sample mean FEV1 of 2.05 liters. Can you conclude that the mean FEV1 in the high-pollution community is less than 2.1 liters? Use the =α0.10 level of significance and the P-value method with the TI-84 calculator.
