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 30 different vehicle models were collected:
Y (Accel Time) : Acceleration time in sec.
X1 (Engine Size) : c.c.
X2 (Sedan) : 1 if the vehicle model is a sedan and 0 otherwise
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.
The coefficient of partial determinations
and
are 0.3301,and 0.0594,respectively.
The coefficient of determination for the regression model using each of the 2 independent variables as the dependent variable and the other independent variable as independent variables ( ) are,respectively 0.0077,and 0.0077.
-Referring to Table 14-16,what is the correct interpretation for the estimated coefficient for X2?
Lack of Capacity
A legal term referring to an individual's inability to enter into a contract due to mental incompetence or age.
Duress
Unlawful pressure exerted upon a person to coerce them into an action against their will, often making a contract voidable.

Affirming Contract
The act of formally agreeing to the terms of a contract, thereby making it legally binding.
