Time Left: 1:53:08 In a scatter diagram, what is showing? the dependent variable is scaled along the horizontal axis. the independent variable is scaled along the vertical axis. O the graph shows the relationship between two variables. O the probabilities are plotted. Question 3 (Mandatory) (1 point) In correlation analysis, the independent variable is O the variable that is scaled on the vertical axis. the variable that is being predicted or estimated. a variable that provides the basis for estimation. It is the predictor variable. None of these answers are correct. Question 4 (Mandatory) (1 point) Suppose we developed the following least squares regression equation: Y =3.5 + 2.1x What of the following statements can we conclude? The dependent variable increases 3.5 for an increase of 1 in X. The equation crosses the Y-axis at 2.1. If X = 5, then is 14. O There is a significant positive relationship between the dependent and independent variables. SAMSUNG
