The graph of the simple linear regression equation is a(n) d. straight line. The scatter chart below displays the residuals verses the independent variable, x . Which of the following conclusions can be drawn from the scatter chart given below? a. The residuals have a increasing variance as the independent variable increases. The difference between the observed value of the dependent variable and the value predicted using the estimated regression equation is known as the b. residual. The population parameters that describe the y -intercept and slope of the line relating y and x , respectively, are c. β 0 and β 1 . ______________ refers to the degree of correlation among independent variables in a regression model. b. Multicollinearity What would be the coefficient of determination if the total sum of squares (SST) is 23.29 and the sum of squares due to regression (SSR) is 10.03? b. 0.43 In a linear regression model, the variable (or variables) used for predicting or #### You've reached the end of your free preview.
