SCENARIO 17-9
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.
-Referring to Scenario 17-9, what is the p-value of the test statistic to determine whether SUV
makes a significant contribution to the regression model in the presence of the other independent
variables at a 5% level of significance?
Nonproportionally
Describes scaling or adjusting components in a way that does not maintain consistent ratios among dimensions.
Corner Sizing Handle
A visual indicator, usually found at the corner of selected objects or windows, that allows users to click and drag to resize the element proportionally.
Middle Sizing Handle
A graphical handle found in the center of an object's side in graphical interfaces, allowing for adjustment in size along one dimension.
Aspect Ratio
The proportional relationship between the width and height of an image or display screen.
