A trucking company keeps track of the number of miles each of its drivers logs each week. Describe the correlation between: the number of miles a driver logs and the drivers age.

• There is a positive correlation. Meaning: as their age increases so do the number of miles

• There is a negative correlation. Meaning: as their age increases, the number of miles the drive decreases

• There is no correlation because the drivers age does NOT impact the number of miles they drive.

• There is a not enough information.
