Jack Tomsky´s evaluation is WRONG. Correct z = 2.0261 and p=0.9786. The EXACT METHOD (by binomial terms summation) gives p(EXACT) = 0.9752864841

So you confirm that my binomial calculation of 0.9753 was correct.Jack

NO. The ONLY thing that it is proved is that Jack Tomsky DO NOT KNOW how to use the normal approximation to evaluate p(X<=30) when X has a binomial distribution
THEREFORE
