weird question

An analyst constructed the following hypothesis test: H0: b = 0 H1: b > 0 The null hypothesis means that: A. the dependent variable is sensitive to changes in the independent variable. B. the independent variable is sensitive to changes in the dependent variable. C. changes in the dependent variable do not explain changes in the independent variable. D. changes in the independent variable do not explain changes in the dependent variable. pls help…

The answers seem completely unrelated to the question and the statement of the hypothesis seems wrong. D!

This is a regression problem which has been moved to LII. (Answer is D, btw)
