**Statistical Analysis:**

- **Pearson Correlation Coefficient (r):** \( r = -0.974 \) (Rounded to three decimal places)

**(c) Describe the type of correlation, if any, and interpret the correlation in the context of the data:**

There is a **strong negative linear correlation**.

**Interpret the correlation:**

- **Option F is Correct:** Higher altitudes cause decreases in speeds of sound.

**(d) Use the table of critical values for the Pearson correlation coefficient to make a conclusion about the correlation coefficient. Let \( \alpha = 0.01 \):**

- The critical value is [Blank].
- Therefore, there [is/is not] sufficient evidence at the 1% level of significance to conclude that [Blank] between altitude and speed of sound.

**Note:** Please ensure proper completion of blanks and interpretation of critical values based on provided data.

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.

The correlation coefficient \( r = -0.974 \) (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 strong negative linear correlation.

Interpret the correlation. Choose the correct answer below.

- O A. As altitude increases, speeds of sound tend to increase.
- O B. Higher altitudes cause increases in speeds of sound.
- ● C. As altitude increases, speeds of sound tend to decrease.
- O D. Based on the correlation, there does not appear to be a linear relationship between altitude and speed of sound.
- O E. Based on the correlation, there does not appear to be any relationship between altitude and speed of sound.
- O F. Higher altitudes cause decreases in speeds of sound.

(d) Use the table of critical values for the Pearson correlation coefficient to make a conclusion about the correlation.

The critical value is \( \_\_\_\_ \). Therefore, there \( \_\_\_\_\_\_ \) sufficient evidence at the 1% level of significance to conclude that \( \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \) between altitude and speed of sound. (Round to three decimal places as needed.)
