**Using Confidence Intervals to Determine Margin of Error and Sample Mean**

To find the margin of error and the sample mean using a given confidence interval, apply the following instructions.

**Confidence Interval Provided:**  
(1.51, 2.01)

**Steps:**

1. **Calculate the Margin of Error:**
   - The margin of error is the difference between the sample mean and one of the interval ends.
   - Given Margin of Error: **0.25**  
   (Note: Ensure to round to two decimal places as necessary.)

2. **Determine the Sample Mean:**
   - The sample mean is the midpoint of the confidence interval.
   - Formula: \[(\text{Lower limit} + \text{Upper limit}) / 2\]
   - Enter the calculated sample mean as a whole number or a decimal.
