4) The R squared value for my model is 0.761532 and adjusted is 0.750693. This tells me that the
significance of this model is quite high given how close it is to the highest possible value of 1.
5) The most significant independent variable is the weight of the vehicle and the least significant
variable is the wheelbase based on the effect summary results.
6) The model equation is MPG = 23.29941 + 0.00221 *(engine revs per mile) – 0.53948 *(fuel tank
capacity) + 0.20729 *(wheel base) – 0.00607 *(weight)
a. 23.29941 is the Y intercept
b. 0.00221 = as engine revs per mile increases by 1 unit, MPG increases by 0.00221 units
c. 0.53948 = as the fuel tank capacity increases by 1 unit, MPG decreases by .53948 units
d. 0.20729 = as wheel base increases by 1 unit, MPG increases by .20729 units
e. 0.00607 = as vehicle weight increases by 1 unit, MPG decreases by .00607 units
