question 92

True/False

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, the 0 to 60 miles per hour acceleration time of a coupe is predicted to be 0.7679 seconds lower than that of an SUV.

Definitions:

Average Total Cost

The total cost divided by the number of units produced, calculating the cost to produce an average unit of output.

Chairs

Objects designed for seating, typically consisting of a seat, back, legs, and sometimes armrests, used for various purposes including dining and office work.

MC

Short for Marginal Cost, it is the change in total cost that arises when the quantity produced is incremented by one unit; it is the cost of producing one more unit of a good.

AVC

Average Variable Cost, the cost of labor or material that changes with the level of output or production.
