Answer these questions
![The image shows a task related to data analysis in an educational context. It presents an exercise to understand the relationship between altitude and the speed of sound through a series of questions.
**Exercise:**
The accompanying table shows eleven altitudes (in thousands of feet) and the speeds of sound (in feet per second) at these altitudes. Complete parts (a) through (d) below.
(a) **Display the data in a scatter plot. Choose the correct graph below:**
Options available for graph selection are:
- **A**: Scatter plot with data points forming a descending linear trend.
- **B**: Scatter plot with a steep descending linear trend.
- **C**: Scatter plot with points that do not form a clear trend.
- **D**: Scatter plot with data points forming an ascending linear trend.
(b) **Calculate the sample correlation coefficient \( r \):**
- \( r = \) [Input box]
- Instruction: Round to three decimal places as needed.
(c) **Describe the type of correlation, if any, and interpret the correlation in the context of the data:**
- There is a [drop-down menu] linear correlation.
- Interpretation options (choose the correct answer below):
- **A**: As altitude increases, speed of sound tends to decrease.
**Data Table:**
| Altitude, \( x \) (1000's ft) | Speed of sound, \( y \) (ft/sec) |
|-------------------------------|----------------------------------|
| 0 | 1115.8 |
| 5 | 1097.9 |
| 10 | 1075.9 |
| 15 | 1056.2 |
| 20 | 1036.9 |
| 25 | 1014.7 |
| 30 | 996.5 |
| 35 | 969.5 |
| 40 | 967.9 |
| 45 | 967.9 |
| 50 | 967.9 |
**Analysis:**
The task involves selecting the appropriate scatter plot that corresponds to the data, calculating the correlation coefficient to determine the strength and direction of the relationship, and interpreting the type of correlation. The expected correlation is negative, indicating that as altitude increases, the speed of sound decreases.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3df97ab4-6262-4c33-b8aa-4d9fb25466b6%2F30c21b42-84f5-4f16-a387-6d2ceebf5ca4%2Ffigl1ot_processed.jpeg&w=3840&q=75)

#### (a) Display the data in a scatter plot. Choose the correct graph below:
- **Option A**: The graph displays a scatter plot with altitude (in thousands of feet) on the horizontal axis, ranging from 940 to 1140, and speed of sound (in feet per second) on the vertical axis, ranging from 945 to 1150.
- **Option B**
- **Option C**
- **Option D**
#### (b) Calculate the sample correlation coefficient \( r \):
\[ r = \]
*Round to three decimal places as needed.*
#### (c) Describe the type of correlation, if any, and interpret the correlation in the context of the data:
There is a [dropdown menu] linear correlation.
Interpret the correlation. Choose the correct answer below:
- **Option A**: As altitude increases, speeds of sound tend to decrease.
This analysis will help in understanding the relationship between altitude and the speed of sound. Understanding this relationship can be important for applications in aviation and meteorology, where sound propagation can be affected by altitude changes.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3df97ab4-6262-4c33-b8aa-4d9fb25466b6%2F30c21b42-84f5-4f16-a387-6d2ceebf5ca4%2Fubvqhqk_processed.jpeg&w=3840&q=75)
