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, 807 births consisted of 418 baby girls and 389 baby boys. in analyzing these results, assume that boys and girls are equally likely. a. find the probability of getting exactly 418 girls in 807 births. b. find the probability of getting 418 or more girls in 807 births. if boys and girls are equally likely, is 418 girls in 807 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?
