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 37 couples. Complete parts (a) through (c) below.**a. Find the mean and the standard deviation for the numbers of girls in groups of 37 births.**The value of the mean is μ = [ ].(Type an integer or a decimal. Do not round.)The value of the standard deviation is σ = [ ].(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 35 girls a result that is significantly high? What does it suggest about the effectiveness of the method?**The result [ ] significantly high, because 35 girls is [ ] girls. A result of 35 girls would suggest that the method [ ].(Round to one decimal place as needed.)
