True/False

SCENARIO 18-9
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. The various residual plots are as shown below.

18-64 A Roadmap for Analyzing Data
-True or False: Referring to Scenario 18-9, the 0 to 60 miles per hour acceleration time of a
coupe is predicted to be 0.7679 seconds higher than that of a sedan.
