SOLUTION: If np>=5 and nq>=5, estimate Upper P left parenthesis more than 7 right parenthesis with n=11 and p=0.6 by using the normal distribution as an approximation to the binomial

Question 1066147: If np>=5 and nq>=5, estimate Upper P left parenthesis more than 7 right parenthesis with 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 and, if necessary, fill in the answer box to complete your choice.
A.Upper P (more than 7)=
(Round to four decimal places as needed.)
B.The normal distribution cannot be used.

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 and, if 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)=
(Round to four decimal places as needed.)
B.The normal distribution cannot be used.
