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, 909 births consisted of 464 baby girls and 445 baby boys. In analyzing these results, assume that boys and girls are equally likely. a. Find the probability of getting exactly 464 girls in 909 births. b. Find the probability of getting 464 or more girls in 909 births. If boys and girls are equally likely, is 464 girls in 909 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?
