Question

When water flows across farm land, some soil is washed away, resulting in erosion.   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.

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:

(hint: you may want to calculate r using your calculator)

Answer 1

Association between this two variables is 0.9669
