Question
Consider the following regression equation: 
= 356 + 180x1- 2.5x2. The x1variable is a quantitative variable and the x2variable is a dummy with values 1 and 0. Given this, we can interpret the slope coefficient on variable x2 as follows: Holding x1constant, if the value of x2 is changed from 0 to 1, the average value of y will decrease by 2.5 units.
