Statistical significance test for missing sets?

[Spete]

For my sanity, please help me quantify how bad I'm running.

Variables:

n : number of samples of pocket pairs seeing a flop
s : number of times a set or better is flopped

Constants:
p : probability of flopping a set or better (0.118)

Now I understand the expected value of s is np, and using binomial distribution I can count the probability of hitting s or fewer sets. Unfortunately this doesn't add much information, maybe it tells that I've been unlucky tell me something I didn't know.

My question is, which statistical significance test should I use and how? I know online poker isn't rigged, but getting a decent statistical significance would confirm that I've ran like it was.
