Tell what each of the residual plots to the right indicates

Tell what each of the residual plots to the right indicates about the appropriateness of the linear model that was fit to the data. Choose the best answer for residuals plot (a). The fanned pattern indicates that the linear model is not appropriate. The model\'s predicting power decreases as the values of the explanatory variable increases. The fanned pattern indicates that the linear model is not appropriate. The model\'s predicting power increases as the values of the explanatory variable increases. The scattered residuals plot indicates an appropriate linear model. Choose the best answer for residuals plot (b). The scattered residuals plot indicates an appropriate linear model. The curved pattern in the residuals plot indicates that the linear model is not appropriate. The relationship is not linear. The fanned pattern indicates that the linear model is not appropriate. The model\'s predicting power decreases as the values of the explanatory variable increases.

Solution

The correct option is:

OPTION C: The fanned pattern indicates that the linear model is not appropriate. The models predicting power decreases as the values of the explanatoy variable increases
