18. Gender Selection The Genetics and IVF Institute conducted a clinical trial of the YSORT method designed to increase the probability of conceiving a boy. As of this writing, 291 babies were born to parents using the YSORT method, and 239 of them were boys. a. What is the best point estimate of the population proportion of boys born to parents using the YSORT method? b. Use the sample data to construct a 99% confidence interval estimate of the proportion of boys born to parents using the YSORT method. c. Based on the results, does the YSORT method appear to be effective? Why or why not?

Question
**Gender Selection: Analysis of the YSORT Method**

The Genetics and IVF Institute conducted a clinical trial of the YSORT method, which is designed to increase the probability of conceiving a boy. As of this writing, 291 babies were born to parents using the YSORT method, and 239 of them were boys.

**a. Analysis of Population Proportion**

- **Question:** What is the best point estimate of the population proportion of boys born to parents using the YSORT method?
  
**b. Confidence Interval Construction**

- **Question:** Use the sample data to construct a 99% confidence interval estimate of the proportion of boys born to parents using the YSORT method.

**c. Evaluating Effectiveness**

- **Question:** Based on the results, does the YSORT method appear to be effective? Why or why not?

This scenario evaluates the YSORT method's efficacy by statistically analyzing the proportion of male births and interpreting the confidence intervals derived from the sample data.
