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, 964 births consisted of 504 baby girls and 460 baby boys. In analyzing these results, assume that boys and girls are equally likely.
a. Find the probability of getting exactly 504 girls in 964 births.
b. Find the probability of getting 504 or more girls in 964 births. If boys and girls are equally likely, is 504 girls in 964 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?

Statistical Significance. In an experiment testing a method of
gender selection intended to increase the likelihood that a baby is
a girl, 1000 couples give birth to 501 girls and 499 boys. An
analyst argues that this fails to provide evidence that the method
has any effect, because the probability of getting these results by
chance is 0.487, or almost 50%.

In a test of a gender-selection technique, results consisted of
282 baby girls and 300 baby boys. Based on this result, what is
the probability of a girl born to a couple using this technique?
Does it appear that the technique is effective in increasing the
likelihood that a baby will be a girl? The probability that a girl
will be born using this technique is approximately nothing. (Type
an integer or decimal rounded to three decimal places as
needed.)
