Question
Assume 42% of us have Group O blood. A hospital is conducting a blood drive because its supply of Group O blood is low, and it needs at least 189 donors of Group O blood. If 473 volunteers donate blood, estimate the probability that the number with Group O blood is at least 189. Is the pool of 473 volunteers likely to be sufficient? (a) P(X2 189) = (Round to four decimal places as needed.) (b) What does the result from part (a) suggest? O A. The pool is likely to be sufficient because P(x2 189) is less than 50%. O B. The pool is not likely to be sufficient because P(x2 189) is less than 50%. O C. The pool is not likely to be sufficient because P(x2 189) is more than 50%. O D. The pool is likely to be sufficient because P(x2 189) is more than 50%.
