Sure thing. That's:
(30 choose 2) * (.95^28) * (.05^2)
= 0.258636738
I thought you meant "at least two tests", for obvious reasons. (If 4 tests showed vote rigging, the researchers would still report vote rigging...)

Yes.
- itistoday 17y agoThanks, looks like I'll have to brush up on my stats to analyze this further... But even without direct knowledge of how this works, shouldn't the "goodness" of the tests play a role in the numbers you're using? It doesn't seem to... > I thought you meant "at least two tests", for obvious reasons. Yes, sorry, I did, I guess you meant to say I should subtract 0.553542075 from 1 to get my answer. (just saw earl's post above...)
