SCENARIO 17-9
What are the factors that determine the acceleration time (in sec.) from 0 to 60 miles 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. ft.
HP: Horsepower
MPG: Miles per gallon
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 regression results using acceleration time as the dependent variable and the remaining variables
as the independent variables are presented below.
-Referring to Scenario 17-9, the 0 to 60 miles per hour acceleration time of a
sedan is predicted to be 0.1252 seconds higher than that of an SUV.

The statement seems incorrect as typical 0 to 60 mph acceleration times for sedans and SUVs are much longer than 0.1252 seconds. This value is likely a difference in predicted times, not the actual time itself.
