Original Question

Researchers collected data to examine the relationship between air pollutants and preterm births in Southern California. During the study, air pollution levels were measured by air quality monitoring stations. Specifically, levels of carbon monoxide were recorded in parts per million, nitrogen dioxide and ozone in parts per hundred million, and coarse particulate matter (PM10) in 𝜇g⁄m3. Length of gestation data were collected on 143,196 births between the years 1989 and 1993, and air pollution exposure during gestation was calculated for each birth. The analysis suggested that increased ambient PM10 and, to a lesser degree, CO concentrations may be associated with the occurrence of preterm births.†(a) Identify the main research question of the study. Are levels of carbon monoxide, nitrogen dioxide, ozone, and coarse particulate matter in Southern California too high? Is there an association between air pollution exposure and preterm births in Southern California? What are the average evels of carbon monoxide, nitrogen dioxide, ozone, and coarse particulate matter in Southern California? Is there an association between the levels of carbon monoxide, nitrogen dioxide, ozone, and coarse particulate matter in Southern California? What is the average length of gestation in Southern California?
