Question

election technique is designed to increase the likelihood that a baby will be a girl. In the results of the gender-selection technique, 921 births consisted of 463 baby girls and 458 baby boys. In analyzing these results, assume that boys and girls are equally likely a. Find the probability of getting exactly 463 girls in 921 births b. Find the probability of getting 463 or more girls in 921 births. If boys and girls are equally likely 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. Bas 463 girls in 921 births unusualy high? hnique is effective? the results, does it appear that the gender-selection a. The probability of getting exactly 463 girls in 921 births is (Round to four decimal places as needed.) b. The probability of getting 463 or more girls in 921 births is (Round to four decimal places as needed) If boys and girls are equally likely, is 463 girls in 921 births unusually high? O A. Yes, because 463 girls in 921 births is not tfar from what is expected, given the probability of having a girl or a boy O B. Yes, because 463 girls in 921 births is far from what is expected, given the probability of having a girl or a boy. O C. No, because 463 girls in 921 births is not t from what is expected, given the probability of having a girl or a boy. OD. No. because 463 girls in 921 births is r 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 O B. 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 C. The result from part (a) is more relevant, because one wants the probability of a result that is exactly equal to the one obtained. O D. Neither of the results are relevant. ) and part (b) re equal, so they are equally relevant d. Based on the results, does it appear that the gender-selection technique is effective?
