  2. True False The multiple regression model (MRM) models the association in the population between multiple explanatory variables and a response.

  3. True False The multiple regression model (MRM) models the association in the population between multiple explanatory variables and a response.

  4. True False Deviations of the residuals from normality may suggest an important omitted variable.

  5. True False Deviations of the residuals from normality may suggest an important omitted variable.

  6. True False A scatterplot matrix allows us to determine visually how strong the association is among the different pairs of variables.
