Question
For this problem, use the multiple regression equation below to complete parts (a) and
(b).
Yi=10+5X1i+3X2i
a. Interpret the meaning of the slopes.
If
X1
increases one unit, Y increases 3 units. If
X2
increases one unit, Y increases 5 units.If
X1
increases one unit, Y increases 5 units. If
X2
increases one unit, Y increases 3 units.If
X2
is constant, when
X1
increases one unit, Y increases 5 units. If
X1
is constant, when
X2
increases one unit, Y increases 3 units.If
X2
is constant, when
X1
increases one unit, Y increases 3 units. If
X1
is constant, when
X2
increases one unit, Y increases 5 units.b. Interpret the meaning of the Y-intercept.
The Y-intercept 5 is the estimate of the mean value of Y if
X1
and
X2
are both 0.The Y-intercept 5 is the estimate of the mean value of Y if
X1
is 0.The Y-intercept 10 is the estimate of the mean value of Y if
