QUESTION 13

  1. For a simple linear regression model, the estimated intercept is 5, and the estimated slope is -3, it implies that

    as the independent variable increases by 1 unit, the dependent variable would increase by 5 units.

    as the independent variable increases by 1 unit, the dependent variable would decrease by 3 units.

    as the dependent variable increases by 1 unit, the independent variable would increase by 5 units.

    as the dependent variable increases by 1 unit, the independent variable would decrease by 3 units.

Answer #1

As the independent variable increases by 1 unit, the dependent variable would decrease by 3 units

The independent variable is given in the x axis and the dependent variable is given in the y axis. Slope is the rate of change of y with respect to unit change in x. Here, slope is -3 means, when x increases by 1 unit, y decreases by 1 unit.

    Answer both questions please true or false 16. The slope of the simple linear regression equation represents the average change in the value of the dependent variable per unit change in the independent variable (X). True/False 19. When using simple regression analysis, if there is a strong correlation between the independent and dependent variable, then we can conclude that an increase in the value of the independent variable causes an increase in the value of the dependent variable.
