Air Pollution One of the air pollutants that is measured in selected cities is sulfur dioxide.
This pollutant occurs when fossil fuels are burned. This pollutant is measured in micrograms
per cubic meter (mg/m³). The results obtained from a sample of 24 cities are shown in the
frequency distributions. One sample was taken recently, and the other sample of the same
cities was taken 5 years ago. Construct a histogram and compare the two distributions.
