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, 888 births consisted of 455 baby girls and 433 baby boys. In analyzing these results, assume that boys and girls are equally likely. a. Find the probability of getting exactly 455 girls in 888 births. . Find the probability of getting 455 or more girls in 888 births. If boys and girls are equally likely, is 455 girls in 888 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 455 girls in 888 births is]. (Round to four decimal places as needed.) b. The probability of getting 455 or more girls in 888 births is]. (Round to four decimal places as needed.) If boys and girls are equally likely, is 455 girls in 888 births unusually high? O A. No, because 455 girls in 888 births is far from what is expected, given the probability of having a girl or a boy. O B. Yes, because 455 girls in 888 births is not far from what is expected, given the probability of having a girl or a boy. O C. Yes, because 455 girls in 888 births is far from what is expected, given the probability of having a girl or a boy. O D. No, because 455 girls in 888 births is not far from what is expected, given the probability of having a girl or a boy. 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)? O A. The results from part (a) and part (b) are equal, so they are equally relevant. O B. Neither of the results are relevant. O C. The result from part (b) is more relevant, because one wants the probability of a result that is at least as extreme as the one obtained. O D. The result from part (a) is more relevant, because one wants the probability of a result that is exactly equal to the one obtained
