Question

Consider the following regression model with with a dummy variable d: Which of the following statement is true about the following hypotheses? 0 A. The hypotheses tests whether or not a difference exists as d changes from 0 to 1. O B. The hypotheses tests whether or not the interaction exists. C. When the mull bypothesis is not rejected, we conclude that the interaction exists. 0 D. When the null hypothesis is rejected, we conclude that there is no si gnificant difference in y as d changes from, o to
