Document Summary
The following are characteristics of a sample of sales of units in a condominium: 117 lake lake street lake lake street street lake lake street street street. A linear relationship exists between the dependent variable and the independent variable only if the slope of the regression line is significantly different from zero. If 1 0 then some positive or negative linear relationship does exist between x and y. If 1 = 0 then knowing x does not help in predicting y as no significant linear relationship between x and y exists. H1: 1 0 (there is no significant linear relationship between x and y). (there is a significant linear relationship between x and y). Note that the magnitude of b1, by itself, does not tell us the strength of the linear relationship between x and y. In fact, by changing the units of measurement we can always make b1 larger or smaller.
