Q9. In a simple linear regression model, the slope term is the change in the mean value of y associated with _____________ in x. A) a corresponding increase B) a variable change C) no change D) a one-unit increase
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.
