Verify that if each xi is multiplied by a positive constant c and each yi is multiplied by another positive constant d, the t statistic for testing H0 1 0 versus Ha 1 0 is unchanged in value (the value of will change, which shows that the magnitude of b 1 is not by itself indicative of model utility)

Question: Verify that if each xi is multiplied by a positive constant c and each yi is multiplied by another positive constant d, the t statistic

Verify that if each xi is multiplied by a positive constant c and each yi is multiplied by another positive constant d, the t statistic for testing H0: β1 = 0 versus Ha: β1 ≠ 0 is unchanged in value (the value of will change, which shows that the magnitude of b ^ 1 is not by itself indicative of model utility)?
