B. the number of burglaries committed. C. the number of guns owned. D. whether or not a burglary was committed by a gun owner. 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. The association between flow rate and amount of eroded soil is A. positive. C. neither positive nor negative. D. impossible to determine since both variables are categorical. An important feature of this plot is A. the absence of any association.
