**Confidence Interval Analysis: Margin of Error and Sample Mean**

In this exercise, we explore how to determine the margin of error and the sample mean from a given confidence interval.

**Given:**
Confidence Interval: (0.186, 0.350)

**Tasks:**

1. **Calculate the Margin of Error:**
   - The margin of error is half the width of the confidence interval. To find this, subtract the lower limit from the upper limit of the interval and divide by 2.

2. **Determine the Sample Mean:**
   - The sample mean is the midpoint of the confidence interval. This can be found by averaging the upper and lower limits of the interval.

**Answer Boxes:**
- Enter the calculated margin of error.
- Enter the calculated sample mean.

Use the input fields to submit your answers for each calculation.

Please ensure to use the precision necessary for your particular academic level or subject requirement.
