YSORT Gender Selection MicroSort’s YSORT gender-selection technique is designed to increase the likelihood that a baby will be a boy. In updated results (as of this writing) from a test of MicroSort’s YSORT gender-selection technique, 291 births consisted of 239 baby boys and 52 baby girls (based on data from the Genetics & IVF Institute). Based on these results, what is the probability of a boy born to a couple using MicroSort’s YSORT method?

Does it appear that the technique is effective in increasing the likelihood that a baby will be a boy?
