I've currently got a stat problem that I can't immediatly interpret. I have a dataset that I have done a linear regression test on, and I have now been asked to determine if the mean of the dependent variable is independent of the explanatory variable. I'm assuming this means doing a test to check if beta = 0, that is, a change in the explanatory variable does not result in any change in the dependent variable. Is this correct?

Yes, if the slope is not significantly different from zero, then one would conclude that there is no linear relationship between the two variables.

Good, that's what I assumed. Thanks! – Elswyyr Mar 02 '14 at 13:32
