You wish to determine if there is a positive 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 AgeNumber of Driver Deaths per 100,000
6432
5530
7236
3430
3118
1629
2122
3218
4624
4631


Ho: ρ = 0
Ha: ρ > 0


Find the Linear Correlation Coefficient
    r =


Find the p-value
   p-value =


The p-value is




  • Greater than αα

  • Less than (or equal to) αα




The p-value leads to a decision to




  • Do Not Reject Ho

  • Reject Ho

  • Accept 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.
