**Question 1**

Find the mean for the given data:

| x | f |
|---|---|
| 1 | 2 |
| 2 | 3 |
| 3 | 5 |
| 4 | 4 |
| 5 | 1 |
| 6 | 4 |
| 7 | 5 |
| 8 | 3 |
| 9 | 2 |

**Choices:**

- ○ 6.3
- ○ 5
- ○ 3.1
- ○ none of these answers

**Explanation:**

The table consists of two columns, `x` (the data values) and `f` (the frequencies of these values). To calculate the mean, use the formula:

\[
\text{Mean} = \frac{\sum (x \times f)}{\sum f}
\]

Calculate the sum of the products of `x` and `f`, and divide by the sum of the frequencies `f`. Compare the result with the given options to find the correct answer.
