A gender-selection technique is designed to increase thelikelihood that a baby will be a girl. In the results of thegender-selection technique, 873 births consisted of 452 baby girlsand 421 baby boys. In analyzing these results, assume that boysand girls are equally likely. (Round 4 demicals if needed)
a. Find the probability of getting exactly 452 girls in 873births.
b. Find the probability of getting 452 or more girls in 873births. If boys and girls are equally likely, is 452 girls in 873births 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 thegender-selection technique is effective?
