**Statistical Analysis of a Normally Distributed Population Sample**

**Sample Data:**
A sample of 18 observations taken from a normally distributed population produced the following data:
```
28.1, 27.1, 25.2, 25.5, 31.2, 23.1, 26.2, 24.1, 28.4,
37.1, 23.9, 28.9, 27.6, 25.5, 27.3, 25.4, 22.7, 22.9
```

**Instructions:**
Round your answers to three decimal places.

**a. Point Estimate of \(\mu\):**

Calculate the point estimate (sample mean) of the population mean \(\mu\).

\[
\overline{x} = \boxed{\text{}} 
\]

**b. 95% Confidence Interval for \(\mu\):**

Construct a 95% confidence interval for the population mean \(\mu\).

\[
(\boxed{\text{}}, \boxed{\text{}})
\]

**c. Margin of Error for \(\mu\) in Part b:**

Determine the margin of error for the estimate of \(\mu\) in part b.

\[
E = \boxed{\text{}}
\]
