Essay

Suppose that environmentalists monitor algae levels in a river and determine that there is alinear association between local rainfall and algae levels. The determine that the best fittinglinear model to predict algae cell counts per milliliter from rainfall in inches is:
Algae cell count=229.32+79.81(Rainfall in inches) withr2=0.604 How will a rainfall that is 3 inches above average affect the algae cell count?
