![## Understanding Confidence Intervals
### Part 4 of 5
For a 95% confidence interval, the goal is to calculate the critical value \( z_{\alpha/2} \).
\[ z_{\alpha/2} = \text{[blank input box]} \]
Options available:
- Clear the input
- Reset the input
### Part 5 of 5
For an 85% confidence interval, determine the critical value \( z_{\alpha/2} \).
\[ z_{\alpha/2} = \text{[blank input box]} \]
Options available:
- Clear the input
- Reset the input
---
**Instructions:**
- The critical value \( z_{\alpha/2} \) is used to calculate the margin of error in confidence intervals.
- Selecting the appropriate \( z_{\alpha/2} \) depends on the desired confidence level.
- Use the options to input, clear, or reset your entries as needed.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe2abc9fb-d370-48b0-8372-54389a01b054%2F3d84bf66-e82f-4a05-ab5d-59a34f029354%2Fqw32as_processed.jpeg&w=3840&q=75)
