If np5 and nq5, estimate P(atleast5) with n=13 and p=0.5 by using the normal distribution as an approximation to the binomialdistribution; if np<5 or nq<5, then state that the normal approximation is not suitable.

Select the correct choice belowand, ifnecessary, fill in the answer box to complete it.

A.

P(atleast5)=

nothing

(Round to three decimal places asneeded.)
