Chapter 6: Normal Probability Distributions

That is, given n = 431 and p = 0.5, find P(at least 235 wins). np = nq = = = We want the probability of “at least 235 wins” so we adjust the x value of 235 by using the continuity correction factor: We want the area representing the region bounded by . Convert 234.5 to a z score . Use table A-2 to find the area to the left of _____ = _____ ................
