AW MATH53 Appli Statistics Question 1 Identify whether the variable in the information below is qualitative or quantitative. Government agencies carefully monitor water quality and its effect on wetlands (Reference: Envi ronment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the co ncentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish an d wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen conce ntration (milligrams of nitrogen per liter of water) was determined for each sample. Question options: quantitative qualitative qualitative as well as quantitative neither qualitative nor quantitative Information does not have any variable Mife
