The US Environmental protection agency monitors levels of pollution in the air for cities across the country.
Ozone pollution levels are measured using a 500-point scale; lower scores indicate little health risk, and
higher scores indicate greater health risk. The following data show the peak levels of ozone pollution in
four cities (Birmingham, Alabama: Memphis, Tennessee: Little Rock, Arkasas: and Jackson, ,Mississippi)
for 10 dates for last year.
