Given are data for two variables, x and y. ý = Xi 6 11 Yi 5 8 (a) Develop an estimated regression equation for these data. (Round your numerical values to two decimal places.) x¡ Yi 6 (b) Compute the residuals. (Round your answers to two decimal places.) 5 11 8 15 13 15 18 20 18 19 13 20 30 19 30 Residuals
(c) Develop a plot of the residuals against the independent variable x. Residuals X; 6 6 4 11 2 -2. -4 -6 0 5 8 5 15 13 10 Y; Standardized Residuals 18 19 X 20 30 15 20 25 O (d) Compute the standardized residuals. (Round your answers to two decimal places.) Residuals 6 4 2 -4 -6 0 5 Do the assumptions about the error terms seem to be satisfied? O The plot suggests a funnel pattern in the residuals indicating that the error term assumptions are not satisfied. O The plot suggests curvature in the residuals indicating that the error term assumptions are 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 not satisfied.
