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 48 couples. Complete parts (a) through (c) below. a. Find the mean and the standard deviation for the numbers of girls in groups of 48 births The value of the mean is μ = (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 (Round to one decimal place as needed.) girls or fewer are significantly low. Values of girls or greater are significantly high. (Round to one decimal place as needed.) c. Is the result of 34 girls a result that is significantly high? What does it suggest about the effectiveness of the method? girls. A result of 34 girls would suggest that the method The result (Round to one decimal place as needed.) significantly high, because 34 girls is
