Conduct Inference on the Slope
-If a hypothesis test of the linear relation between the explanatory and the response variable is of the type where $\mathrm { H } _ { 0 } : \beta _ { 1 } = 0 , \mathrm { H } _ { 1 } : \beta _ { 1 } 0$, then we are testing the claim that
A) the slope of the least square regression model is positive.
B) the slope of the least squares regression model is negative.
C) a relationship exist without regard to the sign of the slope.
D) no linear relationship exists.

The hypothesis test $\mathrm { H } _ { 0 } : \beta _ { 1 } = 0 , \mathrm { H } _ { 1 } : \beta _ { 1 } > 0$ is testing whether the slope ($\beta_1$) of the regression line is greater than zero, which implies a positive relationship between the explanatory and response variable.
