a.Find the probability of getting exactly 441 girls in 863 births.

b.Find the probability of getting 441 or more girls in 863 births. If boys and girls are equallylikely, is 441 girls in 863 births unusuallyhigh?

c.Which probability is relevant for trying to determine whether the technique iseffective: the result from part(a) or the result from part(b)?

d. Based on theresults, does it appear that thegender-selection technique iseffective?
