Transcribed Image Text:**Question 11: Determining the Proportion of Spring Semester Students Attending Summer School**
A university planner aims to determine the proportion of spring semester students who will attend summer school. In her survey of 32 current students, she finds that 12 will return for summer school. What is the 90% confidence interval estimate for the proportion of current spring students who will return for summer school?
**Options:**
- 0.234 to 0.516
- 0.204 to 0.486
- 0.144 to 0.426
- 0.174 to 0.456
**Correct Answer Selected:**
- 0.174 to 0.456
**Explanation:**
The problem involves calculating a 90% confidence interval for the proportion of students who will attend summer school. Given the sample size and the number of students returning, this interval helps provide a range in which the true proportion of students is likely to fall, with 90% certainty.
