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 o=0.4. A random sample of 63 10-year-old boys who live in a community with high levels of ozone pollution are found to have a sample mean FEV₁ of 1.97 liters. Can you conclude that the mean FEV₁ in the high-pollution community is less than 2.1 liters? Use the a=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 left-tailed Part: 1/4 Part 2 of 4 test. Find the 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 FEV₁. Assume the mean FEV₁ for 10-year-old
boys is 2.1 liters and that the population standard deviation is 6=0.4. A
random sample of 63 10-year-old boys who live in a community with high
levels of ozone pollution are found to have a sample mean FEV₁ of 1.97
liters. Can you conclude that the mean FEV₁ in the high-pollution
community is less than 2.1 liters? Use the a=0.10 level of significance and the
P-value method with the TI-84 calculator.
