Please help for part b, thanks. 

**Title: Calculating and Interpreting 95% Confidence Intervals** In this section, we will explore how to calculate and interpret the 95% confidence interval for two different situations. **Situation (a):** - **Sample Size (n):** 734 respondents - **Average Years of School Completed:** 11.9 years - **Standard Deviation:** 0.5 **Situation (b):** - **Sample Size (n):** 668 respondents - **Number Favoring Capital Punishment:** 432 - **Context:** Respondents were questioned on their stance regarding capital punishment for those convicted of murder. In both situations, the goal is to determine the range within which we can say with 95% confidence that the true population parameter lies. *Note: No graphs or diagrams are included in the image.*
