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, 865 births consisted of 434 baby girls and 431 baby
boys. In analyzing these results, assume that boys and girls are equally likely.
a. Find the probability of getting exactly 434 girls in 865 births.
b. Find the probability of getting 434 or more girls in 865 births. If boys and girls are equally likely, is 434 girls in 865 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?
...
If boys and girls are equally likely, is 434 girls in 865 births unusually high?
A. Yes, because 434 girls in 865 births is not far from what is expected, given the probability of having a girl or a boy.
B. Yes, because 434 girls in 865 births is far from what is expected, given the probability of having a girl or a boy.
C. No, because 434 girls in 865 births is not far from what is expected, given the probability of having a girl or a boy.
D. No, because 434 girls in 865 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)?
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. Neither of the results are relevant.
C. The results from part (a) and part (b) are equal, so they are equally 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?
A. No, because the probability of having 434 or more girls in 865 births is not unlikely, and thus, is attributable to random chance.
B. Yes, because the probability of having 434 or more girls in 865 births is not unlikely, and thus, is not attributable to random chance.
C. Yes, because the probability of having 434 or more girls in 865 births is unlikely, and thus, is not attributable to random chance.
D. No, because the probability of having 434 or more girls in 865 births is unlikely, and thus, is attributable to random chance.
