Comparing regression slopes?

I was hoping someone could help me out getting this done in Mathematica:

I have two continuous variables, X and Y that I regress with no intercept,
so the equation ends up being:

Y = MX

My question is, does M significantly differ from some arbitrary value Z (Z
<> 0 in this case)?  How do I do this in Mathematica?  Is there someplace I
can just type in my expected Z and have Mathematica spit out a p-value?
