Part A & B need help
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
428 baby girls and 425 baby boys. In analyzing these results, assume that boys and girls are equally likely.
a. Find the probability of getting exactly 428 girls in 853 births.
b. Find the probability of getting 428 or more girls in 853 births. If boys and girls are equally likely, is 428 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 428 girls in 853 births is
(Round to four decimal places as needed.)
