3. Recall this question from Iectronic Assignments 4. 6 and 7: Suppose that in a population of twins. males [id] and females [F] are enuallyr lilteiyr to occur and the probability that a pair of twins is identical is o. If the twins are not identical, their sexes are independent. Under this model. the probabilities that a pair of twins will be HM. FF. or HF are given by: 1+1: PUHIM) = P(FF] = Tend PdF) = L:- in a sample of SI] independent twin pairs. we observe 16 MM. 14 FF. and 2D HF pairs. From the given information. we determined that d = 0.2. Based on the observed data. what is the observed value of the Pearson Goodness ofFlt test statistic to test the goodness of t of this model? a] 1.12 B] 11.641 C] 1.3 D] 0.133
