npq. = the Directions: An SRS of size 120 is chosen from a population where P(AB type blood) = 0.05. Let number of donors with AB blood. Then X has a binomial distribution with =np and = Further, since both np 5 and ng 5, you may use a normal distribution to approximate probabilities, as long as you make an appropriate continuity correction beforehand. Do these problems using either the skills you learned to compute binomial probabilities or the skills you learned to compute normal probabilities. 8] P(X=7) 9] -4 P(X >10) 0 4 -4 0 10] -4 P(4
