A? gender-selection technique is designed to increase thelikelihood that a baby will be a girl. In the results of the?gender-selection technique,
861861
births consisted of
443443
baby girls and
418418
baby boys. In analyzing these? results, assume that boys andgirls are equally likely.
a. Find the probability of getting exactly
443443
girls in
861861
births.
b. Find the probability of getting
443443
or more girls in
861861
births. If boys and girls are equally? likely, is
443443
girls in
861861
births unusually? high?
c. Which probability is relevant for trying todetermine whether the technique is? effective: the result frompart? (a) or the result from part? (b)?
d. Based on the? results, does it appear thatthe? gender-selection technique is? effective?
