You wish to determine if there is a positive linear correlationbetween the age of a driver andthe 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
78 20
64 28
67 19
34 25
26 36
70 26
63 26
61 31
76 32

Ho: = 0 Ha: > 0

Find the Linear Correlation Coefficient r =

Find the p-value p-value =

The p-value is

  • Less than (or equal to)
  • Greater than

The p-value leads to a decision to

  • Do Not Reject Ho
  • Accept Ho
  • 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 negative 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.
