Q1.In a study of pollution in a water stream, the average concentration(AC) of pollution is measured at 4 different locations. The locations are at different distances to the pollution source (PS). In the table below, these distances and the average pollution are given: Distance to PS (in km) X 2 4 6 8 Average Concentration Y 11.5 10.5 9 7 1- Find the regression line (Estimation Equation) by which we can estimate the AC using the Distance to PS. 2- Predict the average concentration(AC) - Y- at point far from the PS -X- by 10 KM.
