question 170

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 Cargo Vol makes a significant contribution to the regression model in the presence of the other independent variables at a 5% level of significance?

Definitions:

Bond Discount

is the difference between the face value of a bond and its selling price when the bond is sold for less than its face value.

Straight Line Amortization

A method for calculating the periodic reduction in the carrying amount of an intangible asset, spreading the cost evenly over its useful life.

Par Value Bonds

Bonds issued with a fixed face value that is to be repaid at maturity, often different from their market value.

Impairment Loss

The amount by which the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, necessitating a write-down to reflect the reduced value.
