TABLE 15-6 Given Below Are Results from the Regression Analysis on 40

question 67

True/False

TABLE 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 (X₁), the number of years of education received (X₂), the number of years at the previous job (X₃), a dummy variable for marital status (X₄: 1 = married, 0 = otherwise), a dummy variable for head of household (X₅: 1 = yes, 0 = no) and a dummy variable for management position (X₆: 1 = yes, 0 = no).
The coefficient of multiple determination (R) for the regression model using each of the 6 variables Xⱼ 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 Table 15-6, the model that includes X₁, X₅ and X₆ should be among the appropriate models using the Mallow's Cp statistic.

Definitions:

Efferent Neurons

Nerve cells that convey impulses away from the central nervous system to effectors, such as muscles or glands.

Synaptic Gap

The tiny space between neurons across which neurotransmitters travel to carry signals from one neuron to another.

Axon Terminal

The very end of the axon of a neuron, where neurotransmitters are released to communicate with other neurons.

Dendrite

Branch-like extensions of a neuron that receive signals from other neurons.
