Question 2 In the regression equation, what does the letter Y represent? The dependent variable The independent variable The slope of the line The Y-intercept Question 3 If the coefficient of determination is 0.94, what can we say about the relationship between two variables? The direction of the relationship is negative. The strength of the relationship is 0.94. Ninety-four percent of the total variation of the dependent variable is explained by the independent variable. The direction of the relationship is positive. Question 4 Based on the regression equation, we can measure the association between two variables measure cause and effect O predict the value of the independent variable given a value of the dependent variable O predict the value of the dependent variable given a value of the independent variable Question 5 If the correlation between two variables is close to 0.5, the linear association between the variables is zero O moderate O strong O weak
