For which binomial distribution would a normal approximation be most acceptable?
A)n = 50, π = 0.05
B)n = 100, π = 0.04
C)n = 40, π = 0.25
D)n = 400, π = 0.02

Question

Quizplus · Accepted Answer

A normal approximation is most acceptable when both np and n(1-p) are greater than or equal to 5. For option C, n = 40 and π = 0.25, np = 10 and n(1-p) = 30, both of which satisfy this condition.
