TABLE 15-5 What Are the Factors That Determine the Acceleration Time (In

question 34

Short Answer

TABLE 15-5
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.
ANOVA
The various residual plots are as shown below.
The coefficient of partial determination ( ) of each of the 5 predictors are, respectively, 0.0380, 0.4376, 0.0248, 0.0188, and 0.0312.
The coefficient of multiple determination for the regression model using each of the 5 variables as the dependent variable and all other X variables as independent variables ( ) are, respectively, 0.7461, 0.5676, 0.6764, 0.8582, 0.6632.
-Referring to Table 15-5, what is the value of the test statistic to determine whether Cargo Vol makes a significant contribution to the regression model in the presence of the other independent variables at a 5% level of significance?

Definitions:

Chunk Information

A strategy used to break down information into smaller, more manageable parts for easier understanding or recall.

Short-term Memory

The short-duration, limited-capacity memory component in which selected input from the memory store is worked on.

Sensory Memory

A very short-term memory that holds sensory information, allowing individuals to retain impressions of sensory information after the original stimulus has ceased.

Encoded

The process of converting information into a different form or code, usually for the purpose of secrecy, storage, or transmission.
