Question
Transcribed Image Text: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 liters and
that the population standard deviation is o = 0.4. A random sample of 78 10-year-old boys who live in a community with high levels of ozone pollution is found
to have a sample mean FEV, of 2.07 liters. Can you conclude that the mean FEV, in the high-pollution community differs from 2.1 liters? Use the a = 0.10 level
of significance and the critical value method with the table.
