If np ≥ 5 and nq ≥ 5, estimate P(more than 5) with n=11 and p=0.4 by using the normal distribution as an
approximation to the binomial distribution; if np <5 or nq <5, then state
that the normal approximation is
not
suitable.
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
OA. P(more than 5)=
(Round to four decimal places as needed.)
B. The normal distribution cannot be used.
