**Car's Fuel Efficiency**

*Source: Rossman/Chance Workshop Statistics, 2nd ed.*

The table below reports the EPA's city miles per gallon rating and the weight (in pounds) for the sports cars described in *Consumer Reports 1999 New Car Buying Guide*. (EPA rating for Audi was not reported.)

| Model                | City MPG | Weight |
|----------------------|----------|--------|
| Audi TT              | -        | 2655   |
| BMW 318Ti            | 26       | 2790   |
| BMW Z3               | 19       | 2960   |
| Chevrolet Camaro     | 17       | 3455   |
| Chevrolet Corvette   | 17       | 3295   |
| Ford Mustang         | 17       | 3270   |
| Honda Prelude        | 22       | 3040   |
| Hyundai Tiburon      | 22       | 2705   |

**A) Observational Units**

Identify the Observational Units here. Determine how many variables are reported in the table for each observational unit, and identify each variable's type (Categorical or Quantitative).

**Boxed Note:**

The simplest graph for displaying two **quantitative variables** simultaneously is a **scatterplot**. A dot is placed for each observational pair at the intersection of its two values. The variable to be predicted (the **Response Variable**) is usually on the vertical axis, while the variable to do the predicting (the **Explanatory Variable**) is on the horizontal axis.

**B) Scatterplot Construction**

Use the provided axes to construct a scatterplot of miles per gallon versus weight.

**Miles per Gallon vs Weight Graph:**

- Vertical Axis: "City MPG" ranging from 20 to 30
- Horizontal Axis: "Weight" ranging from 2000 to
