You need the raw data. If you have the number of children n in each group you can fit a binomial regression model by doing glm (prop ~ a, binomial (link="probit"), weight=n). Using the default logit link function instead of the probit would probably make the results easier to interpret (in terms of oddsratios). – Jarle Tufto.
