![**Confidence Interval and Related Calculations**
**Question:**
Suppose we have the following confidence interval: (-1.52, 2.37)
1. **What is the point estimate?** Round to 3 decimal places.
- *Type your answer...*
2. **What is the width of the interval?** Round to 3 decimal places.
- *Type your answer...*
3. **What is the margin of error?** Round to 3 decimal places.
- *Type your answer...*
**Explanation of Calculations:**
- The **point estimate** is the midpoint of the confidence interval and can be calculated as the average of the lower and upper bounds:
\[
\text{Point Estimate} = \frac{-1.52 + 2.37}{2}
\]
- The **width of the interval** is the difference between the upper and lower bounds of the interval:
\[
\text{Width} = 2.37 - (-1.52)
\]
- The **margin of error** is half of the interval width:
\[
\text{Margin of Error} = \frac{\text{Width}}{2}
\]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc6184893-1e67-4ed8-9784-fdd0cf2ed60a%2F294edd9d-5d5d-46d2-8bb6-45c093297aa9%2Fi3wr4rl_processed.jpeg&w=3840&q=75)
