When water flows across farmland, some of the soil washed away, resulting in erosion. An experiment was conducted to investigate the effect of the rate of water flow on the amount of soil washed away. Flow is measured in liters per second and the eroded soil measured in kilograms. The data is given in the following table: Flow rate 0.31 0.85 1.26 2.47 3.75 Eroded 0.82 1.95 2.18 3.01 6.07 Soil What is the association between flow rate and the amount of eroded soil? The association is positive. The association is negative. The association is neither positive nor negative. O It is impossible to determing the association because both variables are categorical
