In Exercises 25-32, find the
25. XSORT Gender Selection MicroSort’s XSORT gender selection technique was designed to increase the likelihood that a baby will be a girl. At one point before clinical trials of the XSORT gender selection technique were discontinued, 945 births consisted of 879 baby girls and 66 baby boys (based on data from the Genetics & IVF Institute). Based on these results, what is the probability of a girl born to a couple using MicroSort’s XSORT method? Does it appear that the technique is effective in increasing the likelihood that a baby will be a girl?
