Transcribed Image Text:### Understanding Spearman’s Rank Correlation Coefficient
Listed below are the number of cricket chirps in 1 minute and the corresponding temperatures in degrees Fahrenheit. The goal is to determine if there is sufficient evidence to conclude that there is a relationship between the number of cricket chirps in 1 minute and the temperature using a significance level of α = 0.05.
#### Collected Data
| Chirps in 1 min | 951 | 861 | 975 | 1103 | 995 | 1120 | 1191 | 1015 |
|-----------------|-----|-----|-----|------|-----|------|------|------|
| Temperature (°F)| 84.5 | 69.8 | 76.9 | 84.6 | 88.7 | 71.4 | 91.8 | 86.8 |
#### Steps to Determine Correlation
1. **Identify the Hypotheses:**
Determine the null (\( H_0 \)) and alternative (\( H_1 \)) hypotheses for this test.
Choose the correct answer from:
- A. \( H_0 : \rho_s \neq 0 \), \( H_1 : \rho_s = 0 \)
- B. \( H_0 : r_s \neq 0 \), \( H_1 : r_s = 0 \)
- C. \( H_0 : \rho_s = 0 \), \( H_1 : \rho_s \neq 0 \)
- D. \( H_0 : r_s = 0 \), \( H_1 : r_s \neq 0 \)
2. **Calculate the Correlation Coefficient:**
Find the value of the Spearman’s rank correlation coefficient (\( r_s \)).
\( r_s = \) (Round to three decimal places as needed.)
3. **Determine the Critical Value(s):**
Using the provided table of critical values of Spearman’s rank correlation coefficient, determine the critical value(s).
Critical value(s) = (Round to three decimal places as needed. Use a comma to separate answers as needed.)
4. **Choosing the Correct Conclusion:**
Based on the calculated correlation coefficient and the critical value(s), choose the correct conclusion.
- A. Fail to reject the null hypothesis. There does not appear to be a
