- 1The Normal distribution as an approximation to the binomialX~B (n,p)
If np>5 and nq>5
X can be approximated by V~N (np,npq)
Continuity corrections apply - 2The normal distribution as an approximation to the poisonX~Po(¥)
If ¥>15
X can be approximated by Y~N(¥,¥)
Continuity corrections apply - 3The poison as an approximation to the binomialX~B(n,p)
If n>50 and np<5
X can be approximated by W~Po(np)
