I think so, though I would normally not think in those terms when it
comes to this kind of models. I would tend to think of the indirect
through yr89 as a mechanism explaining (part of) the effect of ed on
warm. So I would think of the null hypothesis of this test as "the
mechanism contributes nothing to the effect of ed on warm".

Hope this helps,
