question 183

Short Answer

TABLE 13-16
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.





The coefficient of multiple determination for the regression model using each of the 5 variables Xj as the dependent variable and all other X variables as independent variables (Rj2) are, respectively, 0.7461, 0.5676, 0.6764, 0.8582, 0.6632.
-Referring to Table 13-16, 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?

Nonconforming Behavior

Actions or attitudes that deviate from societal norms or expectations, often challenging traditional values.

Peers Pressure

The influence exerted by a peer group in encouraging a person to change their attitudes, values, or behaviors in order to conform to group norms.

Variable-Ratio Schedules

A reinforcement schedule in behavioral psychology where a response is reinforced after an unpredictable number of responses, promoting a high and steady rate of response.

Reinforcement Schedules

Involves the structured application of rewards or punishments to modulate behavior within a learning process, emphasizing the timing and frequency.
