Do the assumptions about the error terms seem to be satisfied? O 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. O The plot suggests a funnel pattern in the residuals indicating that the error term assumptions are not satisfied. O 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. (d) Compute the standardized residuals.

O The standardized residual plot has the same shape as the original residual plot. The plot suggests a generally horizontal band of residual points indicating that the error term assumpt are not satisfied. O The standardized residual plot has the same shape as the original residual plot. The plot suggests curvature in the residuals indicating that the error term assumptions are not satisfies The standardized residual plot has a different shape than the original residual plot. The plot suggests a funnel pattern in the residuals indicating that the error term assumptions are not satisfied. The standardized residual plot has a different shape than the original residual plot. The plot suggests a generally horizontal band of residual points indicating that the error term assumptions are satisfied. The standardized residual plot has a different shape than the original residual plot. The plot suppests curvature in the residuals indicating that the error term assumptions are satisfied.
