A regression [22] of cricket chirps per minute (Y) for one cricket species on temperature in degrees Fahrenheit (X) gave this estimated equation: Y = −0.309 + 0.212X. Which is the dependent and which the independent variable? What is the predicted value of Y when X = 0?When X = 300? Do these predictions seem plausible? Can we judge the reasonableness of this model by the plausibility of these predictions?
