When you doing post hoc analysis of residuals to test the assumptions of a multiple linear regression model, choose the answer that describes what you would expect to see in each of these graphs, if the model does not violate the assumptions:

Scatteplot of residuals vs Predicted:

a) randomly scattered around zero

b) should be linear

c) approx normally distributed

Graph of actual vs. predicted:

a) randomly scattered around zero

b) should be linear

c) approx normally distributed

Histogram of residuals:

a) randomly scattered around zero

b) should be linear

c) approx normally distributed
