Master the GMAT™ Focus Edition
In the interest of clearing this question from the queue, I will say that not only is the topic--multiple regression--NOT one that is covered on the GMAT™, but the test would also never present a question in a true-or-false format. I wonder if you posted the question in the wrong section, perhaps. It seems more suited to a statistics forum, rather than one dedicated to the GMAT™. I am afraid that this test covers statistics in a simpler way: mean, variance, standard deviation. Moreover, if a model were presented, say, in the IR section, then the question would be oriented more toward the data presented, rather than focusing on how the model had been generated.
Good luck in your studies, whatever those may be.
