Estimation of difference among population proportions

Assume the two proportions be described by P1 and P2, respectively,Then the difference absolute between the two proportions is described by (P1 - P2)

The standard error is described by:-

S(P1 - P2) = √{(pq/n1) + (pq/n2)}  =   where p = (p1n1 + p2n2)/(n1 + n1)  and q = 1 - p

Then described the confidence level, the confidence interval among the two population proportions is described by

(P1 - P2) ± Confidence level S(P1 - P2)

= (P1 - P2) ± Z  √{(pq/n1) + (pq/n2)} 

Whereas P = (p1n1 + p2n2)/(n1 + n1)  always remember to convert P1 and P2 to P.
