**Educational Content on Altitude and Speed of Sound**

The accompanying data table shows eleven altitudes (in thousands of feet) and the corresponding speeds of sound (in feet per second) at these altitudes. Complete the tasks that follow based on this information.

**Data Table:**

| Altitude (thousands of feet) | Speed of Sound (feet per second) |
|------------------------------|----------------------------------|
| 0                            | 1116.4                           |
| 5                            | 1097.7                           |
| 10                           | 1077.9                           |
| 15                           | 1057.7                           |

### Tasks:

**(a) Display the data in a scatter plot.**

Choose the correct graph from the options below:

- **Graph A:** Displays a scatter plot where altitude ranges from 0 to 55 on the x-axis (in thousands of feet) and the speed of sound ranges from 940 to 1140 on the y-axis (in feet per second).

- **Graph B:** Displays a scatter plot where altitude ranges from 0 to 55 on the x-axis (in thousands of feet) and the speed of sound ranges from 940 to 1140 on the y-axis (in feet per second).

### (b) Calculate the sample correlation coefficient \( r \).

- Input the value of \( r \) and round it to three decimal places as needed.
