Correct answers:
- number of hours worked and free time — more work hours ⇒ less free time (negative correlation)
- the speed of a train and the length of time to reach the destination — higher speed ⇒ shorter travel time
- a tadpole’s age and the length of its tail — as tadpoles age, the tail shortens during metamorphosis

(Speed of a car and stopping distance is positive; adult head circumference vs. adult age shows little or no consistent negative correlation.)
