SCENARIO 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
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 Scenario 14-16, which of the following assumptions is most likely violated based on the normal probability plot?
