K possible If np 5 and nq 5, estimate P(more than 7) with n = 13 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. OA. P(more than 7)= (Round to four decimal places as needed.) OB. The normal distribution cannot be used.
