TABLE 14-12
As a project for his business statistics class,a student examined the factors that determined parking meter rates throughout the campus area.Data were collected for the price ($)per hour of parking,blocks to the quadrangle,and whether the parking is on or off campus.The population regression model hypothesized is Y_i = α + β₁X_1i + β₂X_2i + ε
where
Y is the meter price per hour.
X₁ is the number of blocks to the quad.
X₂ is a dummy variable that takes the value 1 if the meter is located on campus and 0 otherwise.
The following Excel results are obtained.
-True or False: An interaction term in a multiple regression model may be used when the relationship between X₁ and Y changes for differing values of X₂.
