            ou wish to determine if there is a negative 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 0.05 and
round all values to 4 decimal places.
| Driver Age | 
Number of Driver
Deaths per 100,000 | 
| 62 |

Ho: ρ = 0
Ha: ρ < 0
Find the Linear Correlation Coefficient
r =
Find the p-value
p-value =
The p-value is
- Less than (or equal to) αα
 
- Greater than αα
 
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 age
and number of driver deaths.
 
- There is a significant negative 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.
 
- There is insufficient evidence to make a conclusion about the
linear correlation between driver age and number of driver
deaths.
