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.

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

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

Question 21Which of the following statements about the regression line is not correct?1 pointTheconstant indicates the place where the regression line crosses the Y-axis. The regression line is the line of which the sum of the residuals is the smallest.The regression line can run horizontally.The regression coefficient is the change in the Y value with 1 unit increase in the X value.

What is the slope of the line that passes through the points
