A researcher studying the relationship between drivers' average speed (MPH) on the highway and number of accidents they have been involved in develops the following regression equation: Y = 1.75 + .03(X) . In this example, if a driver's average driving speed is 75 MPH, you would predict he or she would get into ______ accidents
A) .03
B) 1.75
C) 4
D) 75
Drivers' Average Speed
Refers to the mean speed at which drivers operate their vehicles over a certain stretch of road or within a specific area.
Number of Accidents
A count of unintended or unexpected events resulting in damage or injury within a specified period or context.
Regression Equation
A mathematical formula that describes the relationship between one dependent variable and one or more independent variables.

Final Answer :
C
Explanation :
According to the regression equation, the predicted number of accidents is Y = 1.75 + 0.03(X). Substituting X = 75 (the driver's average speed) yields Y = 1.75 + 0.03(75) = 4.25 accidents. Therefore, the best choice is C.
