10.4. Inferences Concerning The Population Regression Coefficients
In Section 9.6, you tested the existence of the slope in a simple linear regression model to determine the significance of the relationship between X and Y. In addition, you constructed a confidence interval of the population slope. In this section, these procedures are extended to the multiple regression model.
