Webn (sample size)=100, p1=.59, p2=.41 st error (of a proportion) = sqrt [ (.59) (.41)/100] z score = (observed-expected rate)/st error or z score = (0.59-0.5)/st error = 1.83 Using the z table to look up 1.83 you'll find your answer (will be slightly off because of rounding). You'll have to subtract the looked-up value from 1.
