4). recall that the researchers want to model the nitrate concentration, y (milligrams per liter), in a rain water sample as a function of two independent variables: water source (groundwater, subsurface flow, or overground flow) and silica concentration (milligrams per liter). (a) write a first-order model for e(y) as a function of the independent variables. assume that the rate of increas
