### Constructing a Relative Frequency Distribution for 2013 Sales

Construct a relative frequency distribution for the 2013 sales. Round the answers to at least three decimal places.

| Manufacturer     | Relative Frequency |
|------------------|--------------------|
| General Motors   |                    |
| Ford             |                    |
| Chrysler LLC     |                    |
| Toyota           |                    |
| Honda            |                    |
| Nissan           |                    |

### Instructions:

1. **Identify Total Sales**: Gather the total sales for each manufacturer for the year 2013.
2. **Calculate Relative Frequency**: Each entry under "Relative Frequency" is calculated by dividing the sales of one manufacturer by the total sales of all manufacturers combined.
3. **Round the Numbers**: Ensure that each relative frequency is rounded to at least three decimal places for accuracy.
4. **Complete the Table**: Fill in the relative frequencies for each manufacturer in the corresponding column.

### Example Calculation:

Suppose the total sales for all manufacturers combined is 1,000,000 units, and General Motors sold 200,000 units. The relative frequency for General Motors would be calculated as follows:

\[ \text{Relative Frequency} = \frac{\text{Sales of General Motors}}{\text{Total Sales}} = \frac{200,000}{1,000,000} = 0.200 \]

You would then enter 0.200 in the relative frequency column for General Motors. Repeat similar calculations for the other manufacturers.

### Visual Explanation:

This table is designed to help you understand the distribution of sales among various car manufacturers in 2013. By expressing sales as relative frequencies, you can compare the proportion of total sales attributed to each manufacturer easily.
