Consider a simple linear regression model When testing H0 1

Consider a simple linear regression model. When testing H0: ?1 = 0 against H1: ?1 ? 0, rejecting the null hypothesis means what?

The slope of the regression line is not zero

There is evidence of a relationship between x and y, but it is not linear

The relationship between x and y is an inverse one

There is not a linear relationship between x and y

There is a linear relationship between x and y

Solution

Note that for linear regression,

Ho: B1 = 0
H1: B1 =/ 0

Thus, rejecting the null hypothesis Ho means accepting B1, that is:

OPTION A: The slope of the regression line is not zero. [ANSWER, A]
