Question 1011626: Help please!
If np ≥5 and nq ≥5, estimate P(more than 6 right) with n=14 and p=0.3 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.
A.
P(more than 6)=
(Round to four decimal places as needed.)
B.
The normal distribution cannot be used.

You can put this solution on YOUR website! If np ≥5 and nq ≥5, estimate P(more than 6 right) with n=14 and p=0.3 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.

np = 14*0.3 = 4.2 ; nq = 14*0.7 = 9.8
