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 ls 0.5. Assume that the groups consist of 17 couples. Complete parts (a) through (c) below.
The value of the mean is 
= ____
(Type an integer or a decimal. Do not round.)
The value of the standard deviation is 
= ____
(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.)
Values of ____ girls or greater are significantly high.
(Round to one decimal place as needed.)
c. Is the result of 15 girls a result that is significantly high? What does it suggest about the effectiveness of the method?
The result ____ significantly high, because 15 girls is ____ ____ girls. A result of 15 girls would suggest that the method ____
