Question
### Scatter Diagrams Analysis

#### Instruction:
Select a scatter diagram with the number of rooms on the horizontal axis and the cost per night on the vertical axis.

#### Scatter Diagram Options:

**A.**
- **X-axis (Horizontal):** Number of Rooms
- **Y-axis (Vertical):** Cost/Night ($)
- **Description:** The data points are spread throughout the graph, showing no clear pattern or correlation between the number of rooms and cost per night.

**B.**
- **X-axis (Horizontal):** Number of Rooms
- **Y-axis (Vertical):** Cost/Night ($)
- **Description:** This graph also shows a scattered distribution of data points with no apparent correlation between the number of rooms and the cost per night.

**C.**
- **X-axis (Horizontal):** Number of Rooms
- **Y-axis (Vertical):** Cost/Night ($)
- **Description:** This diagram displays a scattered arrangement with no clear trend or correlation between the cost per night and the number of rooms.

**D.**
- **X-axis (Horizontal):** Number of Rooms
- **Y-axis (Vertical):** Cost/Night ($)
- **Description:** The scatter plot shows data points spread across the graph without an obvious pattern, indicating no clear relationship between room numbers and nightly cost.

#### Selection:
Choose the scatter diagram that best represents the relationship or lack thereof between the number of rooms and the cost per night based on the given graphs. If no pattern is evident, any diagram might be suitable to represent a lack of correlation.
