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 forced expiratory volume in one second, and is abbreviated FEV Assume the mean FEV, for 10-year-old boys is 2.1 liters and that the population standard deviation is o 0.4. A random sample of 69 10-year-old boys who live in a community with high levels of ozone pollution are found to have a sample mean FEV, of 2.0 liters. Can you conclude that the mean FEV, in the high-pollution community is less than 2.1 liters? Use the a 0.01 level of significance and the P.value method with the TI-84 calculator. Part 1 of 4 State the appropriate null and alternate hypotheses. Ho u- 2.1 Hu< 2.1 This hypothesis test is a left-tailed v test. Part: 1/4 Part 2 of 4 Find the P-value. Round the answer to at least four decimal places. P-value =

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 forced expiratory volume in one second, and is abbreviated FEV,. Assume the mean FEV, for 10-year-old boys is 2.1 liters and that the population standard deviation is o = 0.4. A random sample of 69 10-year-old boys who live in a community with high levels of ozone pollution are found to have a sample mean FEV, of 2.09 liters. Can you conclude that the mean FEV, in the high-pollution community is less than 2.1 liters? Use the a = 0.01 level of significance and the P-value method with the TI-84 calculator. Part 1 of 4 State the appropriate null and alternate hypotheses. Ho: u = 2.1 Hu< 2.1 This hypothesis test is a left-tailed test. Part: 1/4 Part 2 of 4 Find the P-value. Round the answer to at least four decimal places. P-value =
