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 33 couples. Complete parts (a) through (c) below. a Find the mean and the standard deviation for the numbers of girls in groups of 33 births. The value of the mean is u= (Type an integer or a decimal. Do not round.) The value of the standard deviation is a (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 girts or fewer are significantly low. (Round to one decimal place as needed.) Values of girls or greater are significantly high. (Round to one decimal place as needed.)

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question C. Because 30 girls is (equal to, greater than, less than)
That the method (is not effective, is effective)
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 33 couples. Complete parts (a) through (c) below.
a. Find the mean and the standard deviation for the numbers of girls in groups of 33 births.
The value of the mean is u=
(Type an integer or a decimal. Do not round.)
The value of the standard deviation is a=
(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 girts or fewer are significantly low.
(Round to one decimal place as needed.)
Values of 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
significantly high, because 30 girls is
