Multiple Choice

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.

-Referring to Scenario 18-9, what is the correct interpretation for the estimated coefficient for
Sedan?

• A) The mean 0 to 60 miles per hour acceleration time of a sedan is estimated to be 0.6427 seconds higher than that of a coupe after considering the effect of all the other Independent variables in the model.
• B) The mean 0 to 60 miles per hour acceleration time of a sedan is estimated to be 0.6427 seconds higher than that of an SUV after considering the effect of all the other Independent variables in the model.
• C) The mean 0 to 60 miles per hour acceleration time of a sedan is estimated to be 0.6427 seconds lower than that of a coupe after considering the effect of all the other Independent variables in the model.
• D) The mean 0 to 60 miles per hour acceleration time of a sedan is estimated to be 0.6427 seconds lower than that of an SUV after considering the effect of all the other Independent variables in the model.
