Question
Please help with this question, don’t know why my answers are wrong. It’s statistics.
![**Confidence Interval Exercise**
In a survey of 45 individuals, we aimed to determine the proportion of Americans who lease a vehicle. Out of those surveyed, 15 individuals stated they lease a vehicle. We need to calculate the 92% confidence interval for the proportion of all Americans who lease a vehicle. Please enter your answers accurate to two decimal places in the provided fields.
_[Input Fields for Confidence Interval: … to …]_
**Question:**
Can we conclude that the proportion of all Americans who lease a vehicle is more than 0.24?
- Yes
- No
- Not enough information to determine this
**Assumptions for Confidence Interval:**
Beyond representative sampling, what assumptions are needed to satisfy the requirements for this confidence interval?
- \( X \sim \text{normal} \) and \( n \geq 30 \)
- \( X \sim \text{normal} \text{ or } n \geq 30 \)
- \( X \sim \text{binomial}, np \geq 5 \text{ and } nq \geq 5 \)
- \( X \sim \text{binomial} \) and at least 5 successes and failures
