The graph of the simple linear regression equation is a(n)d. straight line.The scatter chart below displays the residuals verses theindependent variable,x. Which of the following conclusions canbe drawn from the scatter chart given below?a. The residuals have a increasing variance as the independent variableincreases.The difference between the observed value of the dependent variable and the valuepredicted using the estimated regression equation is known as theb. residual.The population parameters that describe they-intercept and slope of the linerelatingyandx, respectively, arec. β0and β1.______________ refers to the degree of correlation among independent variables in aregression model.b. Multicollinearity
