Problem 17BSC

Gender Selection The Genetics & IVF Institute conducted a clinical trial of the XSORT method designed to increase the probability of conceiving a girl. As of this writing, 945 babies were born to parents using the XSORT method, and 879 of them were girls.

a. What is the best point estimate of the population proportion of girls born to parents using the XSORT method?

b. Use the sample data to construct a 95% confidence interval estimate of the proportion of girls born to parents using the XSORT method.

c. Based on the results, does the XSORT method appear to be effective? Why or why not?

Step-by-Step Solution:
Step 1 of 3

Solution 17BSC

1. The point estimate of the population proportion is =0.930.
2. The 95% confidence interval for the population proportion p is 0.914<p<0.946.
3. The estimated population proportions of the girl child born is greater than 0.5 and hence we can conclude that the XSORT method is effective in increasing the probability of girl child birth.
