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 Rolhood that each baby will be a girl, but assume that the method has no effect, so the probability of a girls 0.5. Assume that the groups consist of 34 couples Complete parts (a) through (c) below. 

a. Find the mean and the standard deviation for the numbers of girls in groups of 34 births The value of the mean is - Type an integer or a decimal. Do not round) The value of the standard deviation - (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 meded.) Values of girls or greater are significantly high. (Round to one decimal place as needed.) 

c. is the result of gins a result that is significantly high? What does it suggest about the effectiveness of the method? There significantly high, because 30 girls is giris. A result of 30 gets would support all the method (Round to one decimal place as needed.)
