ealth of a person's lungs is the amount of air a person can exhale under force n one second. This is called forced expiratory volume in one second, and is bbreviated FEV₁. Assume the mean FEV₁ for 10-year-old boys is 2.1 liters and hat the population standard deviation is o=0.5. A random sample of 58 10-year- Id boys who live in a community with high levels of ozone pollution are found o have a sample mean FEV₁ of 1.98 liters. Can you conclude that the mean EV₁ in the high-pollution community differs from 2.1 liters? Use the a=0.10 leve f significance and the P-value method with the TI-84 calculator. Part 1 of 4 State the appropriate null and alternate hypotheses

Question
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 FEV₁. Assume the mean FEV₁ for 10-year-old boys is 2.1 liters and that the population standard deviation is 6=0.5. A random sample of 58 10-year- old boys who live in a community with high levels of ozone pollution are found to have a sample mean FEV₁ of 1.98 liters. Can you conclude that the mean FEV₁ in the high-pollution community differs from 2.1 liters? Use the α=0.10 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: μ = 2.1 H₁:μ #2.1 This hypothesis test is a two-tailed Part: 1 / 4 Part 2 of 4 test. Find the P-value. Round the answer to at least four decimal places. P-value:
