You 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 0.01 and round all values to 4 decimal places. Driver Age Number of Driver Deaths per 100,000 31 23 60 27

Ho: ρ = 0
Ha: ρ < 0
Find the Linear
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 insufficient evidence to make a conclusion about the 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 a significant
positive 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.
