White or Black? - A stats project


White.
You do realize that at best your results can extrapolate to those who have a preference, right? And the self-selected nature of the sample introduces the possibility for biases, too. Is 30 the target sample size so that you can use the normal approximation to the binomial?

I dont mind the bias, since I just need results. Yea, I'm supposed to use normal approximation.
OK, for my summer statistics class, I have to a binomial survey/question, aka a question with two outcomes. So my question is: Do you prefer playing as white or as black? Please, no "don't care" or any ambiguous replies, just pick which color you prefer. Need 30 people to reply... Thanks in advance.
