2. Suppose that in a population of twins, males (M) and females (F) are equally likely to occur and the probability that a pair of twins is identical is a. If the twins are not identical, their sexes are independent. Under this model, the probabilities that a pair of twins will be MM, FF, or MF are given by: P(MM) = P(FF) = 1+0 and P(MF) = -0 2 In a sample of 50 independent twin pairs, we observe 16 MM, 14 FF, and 20 MF pairs. Based on the above data, we determined that @ = 0.2. In this case, a = 0.4 is A) implausible based on / in light of the observed data. B) plausible based on / in light of the observed data. C) very plausible based on / in light of the observed data. D) very implausible based on / in light of the observed data
