Webb218 CHAPTER 9. SIMPLE LINEAR REGRESSION 9.2 Statistical hypotheses For simple linear regression, the chief null hypothesis is H 0: β 1 = 0, and the corresponding alternative hypothesis is H 1: β 1 6= 0. If this null hypothesis is true, then, from E(Y) = β 0 + β 1x we can see that the population mean of Y is β 0 for WebbSimple Linear Regression To describe the linear association between quantitative variables, a statistical procedure called regression often is used to construct a model. Regression is used to assess the contribution of one or more “explanatory” variables (called independent variables) to one “response” (or dependent) variable.
