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, 889 births consisted of 450 baby girls and 439 babyboys. In analyzing these results, assume that boys and girls are equally likely.a. Find the probability of getting exactly 450 girls in 889 births.b. Find the probability of getting 450 or more girls in 889 births. If boys and girls are equally likely, is 450 girls in 889 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 450 girls in 889 births is 0.0223.(Round to four decimal places as needed.)b. The probability of getting 450 or more girls in 889 births is(Round to four decimal places as needed.)

(a) The probability of getting exactly 450 girls in 889 births is obtained below as follows: The…
