XSORT Method of Gender Selection When testing a method of gender selection, we assume that the rate of female births is 50%, and we reject that assumption if we get results that are unusual in the sense that they are very unlikely to occur with the 50% rate. In a preliminary test of the XSORT method of gender selection, 14 births included 13 girls. Assuming a 50% rate of female births, find the probability that in 14 births, the number of girls is 13.

Assume that a gender selection method was used by a couple
trying to conceive a girl. Let x be the number of girls in three
births. Assuming that the probability of using this gender
selection method is 63% effective in conceiving a girl, list the
probability distribution of a couple having three children.

Statistical Significance. In an experiment testing a method of
gender selection intended to increase the likelihood that a baby is
a girl, 1000 couples give birth to 501 girls and 499 boys. An
analyst argues that this fails to provide evidence that the method
has any effect, because the probability of getting these results by
chance is 0.487, or almost 50%.

Assume that different groups of couples use a particular method
of gender selection and each couple gives birth to one baby. This
method is designed to increase the likelihood that each baby will
be a girl, but assume that the method has no effect, so the
probability of a girl is 0.5. Assume that the groups consist of 44
couples. Complete parts A to C below.
