question 3

Short Answer

Instruction 16-7
What are the factors that determine the acceleration time (in sec.) from 0 to 60 kilometres per hour of a car? Data on the following variables for 171 different vehicle models were collected:
Accel Time: Acceleration time in sec.
Cargo Vol: Cargo volume in cu. cm.
EP: Engine power
KPL: Kilometres per litre
SUV: 1 if the vehicle model is an SUV with coupe as the base when SUV and sedan are both 0
Sedan: 1 if the vehicle model is a sedan with coupe as the base when SUV and sedan are both 0
The coefficient of multiple determination (R²_j) for the regression model using each of the five variables X_j as the dependent variable and all other X variables as independent variables are, respectively, 0.7461, 0.5676, 0.6764, 0.8582, 0.6632.
-Referring to Instruction 16-7,what is the value of the variance inflationary factor of Cargo Vol?
