A researcher studying the relationship between drivers' average speed (MPH) on the highway and number of moving violations they receive develops the following regression equation: Y'= 1.85 + .05(X). In the example, Y'refers to ______.
A) the Y-intercept
B) the slope of the equation
C) a driver's average speed (MPH)
D) a driver's number of moving violations

Question

Quizplus · Accepted Answer

YF1F1F1S1F1F1F10 represents the number of moving violations a driver receives, which is the dependent variable being predicted based on the independent variable X (average speed). Therefore, the answer is D. The Y-intercept and slope of the equation are represented by 1.85 and .05, respectively. The variable C represents the independent variable (average speed).
