I took a statistics course many years ago in college but I've forgotten most of it as it hasn't been relevant to my field. However I now have a simple problem:

I have daily data for many sellers using a trading system. It counts the number of trades each seller makes and the numbers of trades a seller makes that violates a certain rule. What I am interested in is a simple statistical test that tells me whether each seller's proportion of trades that violate the rule is statistically significant.

I know the proportion of violations in the entire population of trades since I have all the data. I know I could do a one sample test of proportion but I would like the test to work even for a seller with a low amount of trades (or at least tell me that I can ignore sellers with a certain low amount of trades). I also don't understand how to tell if my data follows the assumptions necessary for the test.

Any ideas from someone who knows basic stats?

They aren't straight, you just can't see far enough that the curvature is easily apparent.
