Question 854087: If np is greater than or equal to 5 and nq is greater than or equal to 5 estimate P (more than 7) n=11 and p=.4 by using normal distribution as an approximation to the binomial distribution. If np<5 or nq<5, then state that the normal approximation is not suitable.

If np is greater than or equal to 5 and nq is greater than or equal to 5 estimate P (more than 7) n=11 and p=.4 by using 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 = 11*0.4 = 4.4
nq = 11*0.6 = 6.6
The normal approximation is not suitable.
