Question 512965: When water flows across farm land, some of the soil is 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 is measured in kilograms. The data are given in the following table.
Flow rate .31 .85 1.26 2.47 3.75
Eroded soil .82 1.95 2.18 3.01 6.07
The association between flow rate and amount of eroded soil is positive or negative? how so?

Ans: Amt. of eroded soil increases as flow rate increases.
So the association (slope) is positive.
