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,which of the following assumptions is most likely violated based on the residual plot of the residuals versus predicted Y?
Conditional Equation
An equation that is true for certain values of its variables, often used in algebra to describe a relationship subject to specific conditions.
Identity Equation
An equation that is true for all values of the variable, typically used to express fundamental algebraic properties.
Solve
The process of finding an answer or solution, especially in mathematics by determining the value of variables.
Possible
That which can be done or achieved, within the realm of reality or probability.
