Question
Consider a B(n, p) and a H(A, B, n) where p = A/(A + B) please derive: the variance of hypergeometric =n*(AB/((A + B)^2))*(A+B-n)/(A+B-1) why
Consider a B(n, p) and a H(A, B, n) where p = A/(A + B)
please derive: the variance of
hypergeometric =n*(AB/((A + B)^2))*(A+B-n)/(A+B-1)
why is binomial variance samallerA+B-n> (A+B-1) ?
since factor (A+B-n)/(A+B-1) is less than 1 ; therefore variance of hypergeometric is smaller)
