If I flipped the coin 1000 times and heads came up 600 times, you would know that there is something wrong with the coin.

But if I flipped a coin only 10 times and one side came up 7 times, I wouldn't assume that there was anything wrong with the coin. I would just assume that it was a short-term fluctuation
Actually if you had enough people flip coins 1000 times, you would absolutely expect to have some people get heads 600 times. For all you stat people, the Chi-squared test gives exact numbers of this probablility.

Cmon I know there is a female out there that knows this stuff. I hope she reads this and does the math. Then we need to talk.
