question 186

Short Answer

TABLE 14-16
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 14-16, what is the p-value of the test statistic to determine whether HP makes a significant contribution to the regression model in the presence of the other independent variables at a 5% level of significance?

Definitions:

Horizontal Axis

The x-axis in a graph, generally representing the independent variable in data representation or analysis.

Perfect Complements

Goods that are consumed together in fixed proportions because their use together enhances their combined utility.

Indifference Curves

Graphical representations used in microeconomics to show different combinations of two goods between which a consumer is indifferent, signifying equal levels of utility.

Bliss Point

The optimal quantity of consumption where any further increase or decrease would lead to lower satisfaction or utility.
