A researcher measured amount of soil washed away over an experimental soil bed for various flow rates.
From the data she obtained the following least-squares regression line:
eroded soil y^ = 0.5 + 1.2 x (flow rate)
One of the flow rates used by the researcher was 0.4 liters per second, and for this flow rate the amount of eroded soil was 0.8 kilograms. These values were used in the calculation of the least-squares regression line. What is the residual corresponding to these values?
Select one:
a. -0.18
b. 0.18
c. 0.98
d. 0.8
