Question 6 Not yet answered Points out of 1.00 Flag question What does the standard error of the estimate represent? Choose the correct answer. Select one: Oa. The standard error of the estimate represents the variability in the independent value and sample size. Ob. The standard error of the estimate represents the variability of the residuals. Oc. The standard error of the estimate represents the variability of the dependent values from the predicted values. Question 7 Not yet answered Points out of 1.00 P Flag question If SSR = 21,937 and SSE = 11,355, what is the coefficient of determination? (Use 2 decimal places) Select one: Oa. 0.76 Ob. 0.66 Oc. 0.86 Question 8 Not yet answered Points out of 1.00 P Flag question If SST = 5,634 and SSE = 1,249, what is the coefficient of determination? (Use only two decimal places) Select one: Oa. 0.79 Ob. 0.81 Oc 0.71 Question 9 Not yet answered Points out of 1.00 Flag question If SSE = 12.78 for a sample size of 18, what is the standard error of the estimate? (Use 2 decimal places) Select one: Oa. 0.79 Ob. 0.85 Oc 0.89 Question 10 Not yet answered Points out of 1.00 p Flag question Why should you always carry out a residual analysis as part of a regression model? Select one: a. Residual analysis gives a better estimation of the variability of the independent variable. Ob. Residual analysis helps with estimation of the intercept and the slope of the regression line. Oc Unless a residual analysis is undertaken, you will not know whether the model fit is appropriate for the data. In addition, residual analysis can be used to check whether the assumptions of regression have been seriously violated
