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, 853 births consisted of 438 baby girls and 415 baby boys. In analyzing these results, assume that boys and girls are equally likely. a. Find the probability of getting exactly 438 girls in 853 births. b. Find the probability of getting 438 or more girls in 853 births. If boys and girls are equally likely, is 438 girls in 853 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 exactily 438 girls in 853 births is (Round to four decimal places as needed.) b. The pability of getting 438 or more girls in 853 births is (Round to four decimal places as needed.) If boys and girls are equally likely, is 438 girls in 853 births unusually high? O A Yes, because 438 girls in 853 births is not far from what is expected, given the probability of having a girl or a boy. O B. No, because 438 girls in 853 births is far from what is expected, given the probability of having a girl or a boy. OC. No, because 438 girls in 853 births is not far from what is expected, given the probability of having a girl or a boy. OD. Yes, because 438 girls in 853 births is 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 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. OB. The results from part (a) and part (b) are equal, so they are equally relevant. OC. Neither of the results are relevant. OD. The result from part (a) is more relevant, because one wants the probability of a result that is exactly equal to the one obtained.

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, 853 births consisted of 438 baby girls and 415 baby boys. In analyzing these results, assume that boys
and girls are equally likely.
a. Find the probability of getting exactly 438 girls in 853 births.
b. Find the probability of getting 438 or more girls in 853 births. If boys and girls are equally likely, is 438 girls in 853 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 438 girls in 853 births is.
(Round to four decimal places as needed.)
b. The pbability of getting 438 or more girls in 853 births is
(Round to four decimal places as needed.)
If boys and girls are equally likely, is 438 girls in 853 births unusually high?
A. Yes, because 438 girls in 853 births is not far from what is expected, given the probability of having a girl or a boy.
B. No, because 438 girls in 853 births is far from what is expected, given the probability of having a girl or a boy.
C. No, because 438 girls in 853 births is not far from what is expected, given the probability of having a girl or a boy.
D. Yes, because 438 girls in 853 births is 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 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.
B. The results from part (a) and part (b) are equal, so they are equally relevant.
C. Neither of the results are relevant.
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.
d. Based on the results, does it appear that the gender-selection technique is effective?
