C LE (a) Develop an estimated regression equation for these data. (Round your numerical values to two decimal places.) 8.3556 + 1.6825x (b) Compute the residuals. (Round your answers to two decimal places.) X Residuals 3.28 H GO -2.15 12 -4.88 21 -0.93 20 4.76 (c) Develop a plot of the residuals against the independent variable x. Do the assumptions about the error terms seem to be satisfied? The plot suggests a generally horizontal band of residual points indicating that the error term assumptions are not satisfied. O The plot suggests curvature in the residuals indicating that the error term assumptions are not satisfied. The plot suggests a funnel pattern in the residuals indicating that the error term assumptions are not satisfied. The plot suggests a generally horizontal band of residual points indicating that the error term assumptions are satisfied. The plot suggests curvature in the residuals indicating that the error term assumptions are satisfied. X
