If we are interested in determining whether two variables are linearly related, it is necessary to: A)perform the t -test of the slope b ₁. B)perform the t -test of the coefficient of correlation r . C)either a or b since they are identical. D)None of these choices.

Quizplus · Accepted Answer

Both the t-test of the slope and the t-test of the coefficient of correlation r are methods used to determine if there is a significant linear relationship between two variables. They essentially test the same hypothesis in the context of linear regression, making them identical for the purpose of determining linear relationship.
