Question

An experiment was conducted to investigate the effect of the rate of water flow (liters per second) on the amount of soil (kilograms) washed away. The data are given in the following table.


We found that the correlation is r=0.9593, the standard deviation of the flow rate is 0.4765, and the standard deviation of the amount of eroded soil is 0.7279. Find the equation of the regression line. What is your best guess of the amount of soil washed away if the water flows at rate 0.97 liters per second? Kg (Keep a
