SCENARIO 15-6 Given Below Are Results from the Regression Analysis

question 63

True/False

SCENARIO 15-6 Given below are results from the regression analysis on 40 observations where the dependent variable is the number of weeks a worker is unemployed due to a layoff (Y)and the independent variables are the age of the worker ( ), the number of years of education received ( ), the number of years at the previous job ( ), a dummy variable for marital status ( 1 = married, 0 = otherwise), a dummy variable for head of household ( 1 = yes, 0 = no)and a dummy variable for management position ( 1 = yes, 0 = no). The coefficient of multiple determination ( )for the regression model using each of the 6 variables as the dependent variable and all other X variables as independent variables are, respectively, 0.2628, 0.1240, 0.2404, 0.3510, 0.3342 and 0.0993. The partial results from best-subset regression are given below:
-Referring to Scenario 15-6, the variable x₁ should be dropped to remove collinearity?

Definitions:

Vessel Elements

Cylindrical plant cells that, along with tracheids, facilitate the transport of water and nutrients in plants.

Tracheids

Tracheids are elongated cells in the xylem of vascular plants, serving to transport water and minerals as well as providing structural support.

Carbohydrates

Organic compounds made up of carbon, hydrogen, and oxygen, serving as a major source of energy for living organisms, and found in foods as sugars, starches, and fiber.

Preprophase Band

In plant cells, a dense array of microtubules just inside of the plasma membrane that appears just prior to mitosis and determines the plane in which the cell will divide.
