Question

Suppose that you want to determine whether there is a difference between the distances traveled by an air-filled football and a helium-filled football, and that you have managed to recruit 12 punters of varying abilities to participate in the study.

Describe, in detail, the design of an experiment that does utilize pairing. Choose the best option.

(a) Have each punter kick a ball, with the type determined randomly. Find the difference between the distances kicked.

(b) Have each punter kick each ball, with the ball they kick first determined randomly. Find the difference in the distances kicked for each punter.

(c) Have each punter kick a ball, with the type determined randomly. Find the sum of the distances kicked.

(d) Have each punter kick each ball, with the ball they kick first determined randomly. Find the sum of the distances kicked for each punter.

Answer 1

(b) Have each punter kick each ball, with the ball they kick first determined randomly. Find the difference in the distances kicked for each punter.
