The Editors of a National Automotive Magazine Recently Studied 30

question 129

Multiple Choice

The editors of a national automotive magazine recently studied 30 different automobiles sold in the United States with the intent of seeing whether they could develop a multiple regression model to explain the variation in highway miles per gallon. A number of different independent variables were collected. The following regression output (with some values missing) was recently presented to the editors by the magazine's analysts: Based on this output and your understanding of multiple regression analysis, which of the independent variables is not considered statistically significant if the test is conducted at the 0.05 level of statistical significance?

• A) All the variables in the model are statistically significant.
• B) None of the variables in the model is statistically significant.
• C) Torque and price as tested
• D) Cylinders, torque, and 0 to 60

Definitions:

System of Equations

A set of equations with the same variables, where the solution must satisfy all equations simultaneously.

Hyperbola

A type of smooth curve lying in a plane, consisting of two branches, which are mirror images of each other, and which open away from each other.

Center and Vertices

Key elements in geometry, specifically for ellipses and hyperbolas, where the center is the midpoint of the vertices (the major points).

Method of Substitution

A strategy for solving systems of equations by replacing variables with equivalent expressions to simplify the system.
