Question 1066147
f np>=5 and nq>=5, estimate P(x>7) when n=11 and p=0.6 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&#8203; and, if&#8203; necessary, fill in the answer box to complete your choice.
Note: np = 11*0.6 = 6.6 ; nq = 11*0.4 = 4.4
Since nq< 5, the normal dist cannot be used.
--------------------- 
A.Upper P (more than 7)=
&#8203;(Round to four decimal places as&#8203; needed.) 
B.The normal distribution cannot be used.

Ans:: B
