In analyzing the residuals to determine whether the simple regression analysis satisfies the regression assumptions, which of the following is true?
A) The histogram of the residuals should be approximately bell-shaped.
B) The scatter plot of the residuals against the dependent variable should illustrate that the variation in residuals is the same over all levels of .
C) Neither A nor B are true.
D) Both A and B are true.

The histogram of the residuals should be approximately bell-shaped to satisfy the assumption of normality, and the scatter plot of the residuals against the dependent variable should show constant variance (homoscedasticity) across all levels of the independent variable, indicating both A and B are true.
