question 20

Multiple Choice

Given the simplex tableau for the optimal primal solution,

• A)the values of the dual variables can be found from the c_j − z_j values of the slack/surplus variable columns.
• B)the values of the dual surplus variables can be found from the c_j − z_j values of the primal decision variable columns.
• C)the value of the dual objective function will be the same as the objective function value for the primal problem.
• D)All of these are correct.

Definitions:

Regression Coefficient

A measure in statistics that represents the relationship strength and direction between a dependent variable and an independent variable.

Estimated Value

A value determined through approximation or inference based on statistical models, often used when exact data is unavailable.

Partial Regression Coefficient

A measure that represents the change in the dependent variable for a one-unit change in the predictor variable, holding all other predictors constant.

Coefficient of Determination

A statistical measure, often denoted as \(R^2\), that represents the proportion of the variance in the dependent variable that is predictable from the independent variables.
