Question

Transcribed Image Text:Assume that different groups of couples use a particular method of gender selection and each couple gives birth to
one baby. This method is designed to increase the likelihood that each baby will be a girl, but assume that the
method has no effect, so the probability of a girl is 0.5. Assume that the groups consist of 40 couples. Complete
parts (a) through (c) below.
a. Find the mean and the standard deviation for the numbers of girls in groups of 40 births.
The value of the mean is
= 20 .
(Type an integer or a decimal. Do not round.)
The value of the standard deviation is o = 3.2 .
(Round to one decimal place as needed.)
b. Use the range rule of thumb to find the values separating results that are significantly low or significantly high.
Values of girls or fewer are significantly low.
(Round to one decimal place as needed.)
