Assume they never have twins that the trials are independent with probability 1 2 of a boy and that they are fertile enough to keep producing children indefinitely Mar 2 2017 A probability problem In how many different ways can 5 people sit around a round table? Is the symmetry of the table important? Answer If the symmetry of the table is not taken into account the May 16 2021 When you use a paired T test you are essentially doing a one sample test where your one sample consists of the paired differences between outcomes in two groups
If you create a new sample of these difference values and then apply the formula for a one sample T test you will see that this is equivalent to the paired test Echoing the first answer. Don t bother to convert just model the counts and covariates directly
If you do that and fit a Binomial or equivalently logistic regression model to the boy girl counts you will if you choose the usual link function for such models implicitly already be fitting a covariate smoothed logged ratio of boys togirls. That s the linear predictor
