I agree with the previous comment... In order to interpret right the confidence interval you get when you apply the formula (+- 1.96*(sqrt(p*(1-p)/n), with the normal approximation to binomial distributions, I recommend you reading P values are not error probabilities: an excelente paper by Hubbard & Bayarri.:

I paste the link...

There is also a thread in this forum about interpreting p-values that I find very useful, but I can not find the link.

Kind regards
