A state transportation department is determining the safety of roadways in a locality based on the age of drivers and number of traffic accidents.The department calculates a Pearson correlation coefficient of 0.295.If the critical value for r = 0.330, what could be concluded?
A) The number of traffic accidents is significantly related to the age of drivers.
B) The age of drivers is significantly related to the number of traffic accidents.
C) The age of drivers is not significantly related to the number of traffic accidents.
D) The age of drivers is causally related to the number of traffic accidents they have.

Question

Quizplus · Accepted Answer

The Pearson correlation coefficient of 0.295 is less than the critical value for r of 0.330, which means that the correlation is not statistically significant. Therefore, we cannot conclude that there is a significant relationship between the age of drivers and the number of traffic accidents. Additionally, correlation does not imply causation, so we cannot conclude that the age of drivers causes traffic accidents.
