In a simple regression analysis, the slope represents:A.The estimated value of the dependent variable (Y) when X is zero.B.The point where the regression line intersects the Y-axis.C.The strength of the linear relationship between X and Y.D.The expected change in the dependent variable (Y) for a one-unit change in the independent variable (X).

The slope of a regression line represents:a.The average change in the dependent variable for a unit change in the independent variableb.The intercept of the regression linec.The correlation coefficient between the variablesd.The residual value in regression analysis

In the simple linear regression model Y space equals space a space plus space b X space plus space u, the regression slope b: a. indicates by how many units Y increases, given a one-unit increase in X. b. when multiplied with X will give you the predicted Y. c. represents the elasticity of Y on X. d. indicates by how many percent Y increases, given a one percent increase in X.

What does a negative slope in a regression line indicate?As the independent variable increases, the dependent variable remains constant.As the independent variable increases, the dependent variable also increases.As the independent variable decreases, the dependent variable increases.As the independent variable increases, the dependent variable decreases

In a simple regression analysis, the Y-intercept represents:A.The error term in the model.B.The estimated value of the dependent variable (Y) when X is zero.C.The slope of the regression line.D.The strength of the linear relationship between X and Y.

Which of the following is the correct interpretation of the slope of the regression line?A student who performs 1 point better than another on the upper-level course is likely to perform 1 point worse in the introductory course.A student who performs 1 point worse than another on the upper-level course is likely to perform 1 point better in the introductory course.A student who performs 1 point better than another in the introductory course is likely to perform 10 − 1.4 = 8.6 points better in the upper-level course.A student who performs 1 point better than another on the introductory course is likely to perform 1 point better in the upper-level course.
