Question 1011626
If np &#8805;5 and nq &#8805;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&#8203; distribution; if np<5 or nq<&#8203;5, then state that the normal approximation is not suitable.
----
np = 14*0.3 = 4.2 ; nq = 14*0.7 = 9.8
