T~t(d.o.f.)

I have got my t statistic by using
I am now being asked for the null distribution of this. I assume this means something in the form of a binomial or normal distribution - but this a t distribution right? So I am a little stumped as to what I am being asked.
I think I have done all the maths and working, but am having a little trouble putting names to the different parts of it.
After reading lots of books and Googling a lot, I cannot find many references to a 'null distribution'.
