**Sampling Distribution**

Given the following sampling distribution:

A table with values:

- **X**: -20, -9, -4, 6, 16
- **P(X)**: \( \frac{2}{25} \), \( \frac{9}{100} \), \( \frac{9}{100} \), \( \frac{1}{4} \), \( \frac{1}{20} \)

**Question:**

What is the mean of this sampling distribution?

**Explanation:**

To find the mean of a sampling distribution, you multiply each outcome (\(X\)) by its probability (\(P(X)\)) and then sum these products. The formula for the mean (\(\mu\)) is:

\[
\mu = \sum [X \cdot P(X)]
\] 

Calculate each product, then sum them to find the mean.
