True False The multiple regression model (MRM) models the association in the population between multiple explanatory variables and a response.
True False The multiple regression model (MRM) models the association in the population between multiple explanatory variables and a response.
True False Deviations of the residuals from normality may suggest an important omitted variable.
True False Deviations of the residuals from normality may suggest an important omitted variable.
True False A scatterplot matrix allows us to determine visually how strong the association is among the different pairs of variables.

True False The F-test uses the F-statistic to test the collective effect of all of the explanatory variables on the response.
