You wish to determine if there is a linear correlation between the age of a driver and the number of driver deaths. The following table represents the age of a driver and the number of driver deaths per 100,000. Use a significance level of 0.01 and round all values to 4 decimal places. Driver Age 65 69 48 37 49 27 62 64 r= Ho: p = 0 Ha: p = 0 Find the Linear Correlation Coefficient Find the p-value p-value = Number of Driver Deaths per 100,000 22 22 34 23 28 20 33 33 The p-value is Greater than a O Less than (or equal to) x The p-value leads to a decision to O Do Not Reject Ho O Accept Ho O Reject Ho The conclusion is O There is a significant negative linear correlation between driver age and number of driver deaths. O There is a significant linear correlation between driver age and number of driver deaths. There is insufficient evidence to make a conclusion about the linear correlation between driver age and number of driver deaths. O There is a significant positive linear correlation between driver age and number of driver deaths.

Transcribed Image Text:**Title: Analyzing Linear Correlation Between Driver Age and Number of Driver Deaths**
You wish to determine if there is a linear correlation between the age of a driver and the number of driver deaths. The following table represents the age of a driver and the number of driver deaths per 100,000. Use a significance level of 0.01 and round all values to 4 decimal places.
| Driver Age | Number of Driver Deaths per 100,000 |
|------------|--------------------------------------|
| 69 | 22 |
| 48 | 34 |
| 37 | 23 |
| 47 | 28 |
| 27 | 20 |
| 62 | 33 |
| 64 | 33 |
**Hypotheses:**
- Ho: ρ = 0
- Ha: ρ ≠ 0
**Tasks:**
1. **Find the Linear Correlation Coefficient (r):**
- Calculate the correlation coefficient using the given data to assess the strength and direction of the linear relationship.
2. **Find the p-value:**
- Determine the p-value to evaluate the statistical significance of the correlation.
**Decision Making:**
- Compare the p-value with the significance level (α = 0.01).
- The p-value is:
- Greater than α
- Less than (or equal to) α
- The p-value leads to a decision to:
- Do Not Reject Ho
- Accept Ho
- Reject Ho
**Conclusion:**
Based on the analysis, select the correct conclusion:
- There is a significant negative linear correlation between driver age and number of driver deaths.
- There is a significant linear correlation between driver age and number of driver deaths.
- There is insufficient evidence to make a conclusion about the linear correlation between driver age and number of driver deaths.
- There is a significant positive linear correlation between driver age and number of driver deaths.
