Measuring 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 the forced expiratory volume in one second, and is abbreviated FEV. Assume the mean FEV, for 10-year-old boys is 2.1 iters and that the population standard deviation is o0.4. A random sample of 34 10-year-old boys who live in a community with high levels of ozone polution are found to have a sample mean FEV, of 2.05 liters. Can you conclude that the mean FEV, in the high-pollution community is less than 2.1 iters? Use the a0.10 level of significance and the P-value method with the table. Part: 0/5 Part i of 5 State the appropriate null and alternate hypotheses. H This hypothesis test is a nght-tailed Vtest. right-tailed left-talled two-talled
