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

Scatterplot of residuals vs. predicted:	Choose the correct one >> 1. randomly scattered around zero 2. should be linear 3. Approximately normally distributed.
Histogram of residuals:	Choose the correct one >> 1. randomly scattered around zero 2. should be linear 3. Approximately normally distributed.
Graph of actual vs. predicted:	Choose the correct one >> 1. randomly scattered around zero 2. should be linear 3. Approximately normally distributed.
