Interpret the mean, median, and mode results using this table. Descriptions: Landfill is the number of disposal sites for solid wastes to be recycled. In the process, it entails soil destruction, thus, emitting greenhouse gases. Acid pertains to the emission of sulfur dioxide and nitrogen oxide measured in thousand tons. This results from the burning of fuels by electric utilities or utility coal consumption which is considered as a contributor to the greenhouse emission. Greenhouse is the amount of greenhouse gases in their carbon monoxide equivalent in terms of heating value, wherein heating value is the amount of heat trapped by CO2, measured in million tons.
