question 316

Short Answer

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 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.

The various residual plots are as shown below.






-Referring to 14-16, ________ of the variation in Accel Time can be explained by Cargo Vol while controlling for the other independent variables.

Definitions:

Nominal Or Interval

Categories of measurement scales in statistics where nominal involves labeling without a natural order and interval implies ordered categories with meaningful intervals between values.

Level Of Measurement

The nature of the information within the values assigned to variables, indicating the degree to which mathematical operations can be performed.

Frequency Distribution

A frequency distribution is a summary of data showing the number (frequency) of observations in each of several non-overlapping categories or classes.

Jobs

Positions of employment or activities performed by individuals, often for compensation.
