A slightly higher percentage than expected either had problems or failed in the smoking environment. Also, before the test began, a set of criteria was most likely established ( a cut-off percentage of failures) to determine if there was a significant difference in the two environments. If a statistical difference was shown to be 95% likely (this involves complex engineering statistics), then their original hypothesis is considered valid, and they felt that action be taken based on that.

I know, I sound like a know it all, but I did this kind of work in a manufacturing company a few years back.

and also most of the places where i play or used to play, smoking is not allowed anyway, unless you're serving a small percentage of food, the only thing i'm worried about is people spilling drinks on my laptops,
