MODULE 4. AIR QUALITY AND URBANIZATION
Aside from elevated temperature in urban areas, city development also contributes to the deterioration of air quality. List the 5 cities in West Virginia (except the Washington DC area) that have monitoring stations for air quality. Information about air quality from 5 monitoring sites in West Virginia can be accessed through this website: http://www.epa.gov/air/data/geosel.html. Fill out Table 4 below and indicate the number of days with good air quality for each monitoring site and their corresponding population size (from Table 1). To calculate the number of days with poor air quality, deduct the number of days when air quality was good from 365 days.

Based on Table 4, which among these cities have the best or worst air quality? What is the relationship of urban population (x-axis) and number of days with poor air quality (y-axis)? Create a scatter plot and indicate regression model and r2 value.
