A gender-selection technique is designed to increase the likelihood that a baby will be a girl. In the results of the gender-selection technique,
862862
births consisted of
448448
baby girls and
414414
baby boys. In analyzing these results, assume that boys and girls are equally likely.
a. Find the probability of getting exactly
448448
girls in
862862
births.
b. Find the probability of getting
448448
or more girls in
862862
births. If boys and girls are equally likely, is
448448
girls in
862862
births unusually high?
c. Which probability is relevant for trying to determine whether the technique is effective: the result from part (a) or the result from part (b)?
d. Based on the results, does it appear that the gender-selection technique is effective?
