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.
-True or False: Referring to Table 14-16,the 0 to 60 miles per hour acceleration time of a sedan is predicted to be 0.7264 seconds lower than that of a non-sedan with the same engine size.
Mum Effect
The tendency to avoid communicating unfavourable news to others.
Decoding Problems
The process of interpreting and breaking down complex problems into manageable parts for better understanding and solution.
Non-verbal Communication
The process of conveying a message without the use of words, through gestures, facial expressions, and body language.
Filtering
The tendency for a message to be watered down or stopped during transmission.
