### Constructing a Relative Frequency Distribution

To construct a relative frequency distribution, we need to calculate the relative frequency for each game. The relative frequency is the proportion of the total number of observations that fall within each category, rounded to three decimal places.

Here is a table listing various games along with a placeholder for their respective relative frequencies:

| **Game**                          | **Relative Frequency** |
|-----------------------------------|------------------------|
| Kinect Adventures! (Xbox 360)     | [   ]                  |
| Just Dance 4 (Wii)                | [   ]                  |
| Madden NFL 13 (Xbox 360)          | [   ]                  |
| Assassin’s Creed III (PS3)        | [   ]                  |
| Pokemon Black/White (DS)          | [   ]                  |
| New Super Mario Bros. 2 (3DS)     | [   ]                  |
| Mass Effect 3 (Xbox 360)          | [   ]                  |
| NBA 2K13 (Xbox 360)               | [   ]                  |

**Instructions for Fill Out:**
1. **Count the Frequency:** Determine the number of times each game appears.
2. **Calculate the Total Frequency:** Find the sum of the frequencies for all games.
3. **Compute the Relative Frequency:** By dividing the frequency of each game by the total frequency.
4. **Round Off:** Round the resulting relative frequencies to three decimal places.

### Example Calculation

Assume the following frequency distribution:
- Kinect Adventures! (Xbox 360): 5
- Just Dance 4 (Wii): 7
- Madden NFL 13 (Xbox 360): 4
- Assassin’s Creed III (PS3): 6
- Pokemon Black/White (DS): 9
- New Super Mario Bros. 2 (3DS): 2
- Mass Effect 3 (Xbox 360): 3
- NBA 2K13 (Xbox 360): 4

**Total Frequency:** 5 + 7 + 4 + 6 + 9 + 2 + 3 + 4 = 40

**Relative Frequency Calculation:** For Kinect Adventures!:

\[ \text{Relative Frequency} = \frac{\text{Frequency}}{\text{Total Frequency}} = \frac{5}{40} = 0.125 \]

After rounding to three decimal places, Kinect Adventures! would have a relative
