You wish to determine if there 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 AgeNumber of Driver Deaths per 100,000
5829
2430
6521
4322
2820
7827
6021
5625


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

  • Accept Ho

  • Reject Ho




The conclusion is




  • There is no Significant Correlation

  • There is Significant Linear Correlation between driver age and number of driver deaths.

  • There is Significant Positive Linear Correlation between driver age and number of driver deaths.

  • There is Significant Negative Linear Correlation between driver age and number of driver deaths.

  • There is no Significant Linear Correlation between driver age and number of driver deaths.




The final conclusion is




  • It appears that there is no linear relationship between driver age and the number of driver deaths.

  • It appears that as driver age increases the number of driver deaths increase.

  • It appears that as driver age increases the number of driver deaths decrease.

  • As a person gets older, more driver deaths will occur.
