#### Inferential Methods in Regression

• Verify that residuals are normally distributed.

• Determine if a linear relationship exists between a dependent and independent variables.
• Formulate a hypothesis test to determine if an independent variable is useful for making decisions.
• Construct confidence intervals for mean responses.

#### Analysis of Variance (ANOVA)

• Perform two-way ANOVA designs.
• Interpret the summary output of ANOVA tables.

• Perform hypothesis tests using one-way ANOVA.
