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. (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 13.6 girls or fewer are significantly low. (Round to one decimal place as needed.) Values of 26.4 girls or greater are significantly high. (Round to one decimal place as needed.) c. Is the result of 30 girls a result that is significantly high? What does it suggest about the effectiveness of the method? The result is significantly high, because 30 girls is greater than girls.

Question

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.
(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 13.6 girls or fewer are significantly low.
(Round to one decimal place as needed.)
Values of 26.4 girls or greater are significantly high.
(Round to one decimal place as needed.)
c. Is the result of 30 girls a result that is significantly high? What does it suggest about the effectiveness of the
method?
The result
is
significantly high, because 30 girls is greater than
girls. A result of 30 girls would suggest
that the method is effective.
(Round to one decimal place as needed.)
