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 33
37 19
55 18
20 22
32 29
75 32
30 28

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.
