What Test of Significance is this?

Inspired by Robert Frost’s 1923 Stopping by Woods on a Snowy Evening
By The SIPA Failed Poets Collective

What test of significance is this? I think I know.
Of course it’s not on my cheat sheet though;
So I just sit and stare blankly here
Watching my GPA fall oh so low.

My dearest Doru must think it queer
To see me staring blankly, in abject fear,
Between β, μ, and σ, my brain begins to break,
For this is the most dreaded final of the year.

He catches my eye, as I quake,
To ask if the question contains some mistake.
The only other sound’s the sweep
Of frantic writing and my pounding headache.

The spring outside is so lovely I could weep
But I have a graduation date, I aim to keep,
And many questions to go before I sleep,
And many questions to go before I sleep.
