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, 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.

Definitions:

Goods Offered

The products made available to consumers in the market, including tangible items that satisfy needs or wants.

High Start-Up Costs

The significant initial investment required to establish a new business, which can include expenses related to research and development, manufacturing, marketing, and administrative infrastructure.

Few Competitors

A market condition where only a small number of firms operate, often leading to higher prices and reduced competition.

Oligopoly

Market structure in which relatively few sellers compete and high start-up costs form barriers to keep out new competitors.
