ou wish to determine if there is a negative linear correlationbetween the age of a driver and the number of driver deaths. Thefollowing table represents the age of a driver and the number ofdriver deaths per 100,000. Use a significance level of 0.05 andround all values to 4 decimal places.
| Driver Age | Number of DriverDeaths per 100,000 |
|---|
| 62 | 33 |
| 37 | 19 |
| 55 | 18 |
| 20 | 22 |
| 32 | 29 |
| 75 | 32 |
| 30 | 28 |
Ho: ? = 0
Ha: ? < 0
Find the Linear Correlation Coefficient
r =
Find the p-value
p-value =
The p-value is
- Less than (or equal to) ??
- Greater than ??
The p-value leads to a decision to
- Reject Ho
- Accept Ho
- Do Not Reject Ho
The conclusion is
- There is a significant linear correlation between driver ageand number of driver deaths.
- There is a significant negative linear correlation betweendriver age and number of driver deaths.
- There is a significant positive linear correlation betweendriver age and number of driver deaths.
- There is insufficient evidence to make a conclusion about thelinear correlation between driver age and number of driverdeaths.
