A​ gender-selection technique is designed to increase thelikelihood 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 andgirls 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 whetherthe technique is​ effective: the result from part​ (a) or theresult from part​ (b)?
d. Based on the​ results, does it appear that the​gender-selection technique is​ effective?
