Question
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, 934 births consisted of 481 baby girls and 453 baby boys. In analyzing these results, assume that boys and girls are equally likely. a. Find the probability of getting exactly 481 girls in 934 births. b. Find the probability of getting 481 or more girls in 934 births. If boys and girls are equally likely, is 481 girls in 934 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? a. The probability of getting exactly 481 girls in 934 births is 0.0172 (Round to four decimal places as needed.) b. The probability of getting 481 or more girls in 934 (Round to four decimal places as needed.). Question Viewer
