Answer #1

We know that a regression equation, in which we predict the value of a variable Y, using an explanatory variable X, is given by

Where, is the slope of the regression equation, and is the intercept.

We want to test whether such a linear relationship could be modeled between the two variables; and in doing that, we test whether or not the slope of the regression line is zero.

So, our hypothesis are

So, the given statement is TRUE.
