Peak force (N) on the hand was measured just prior to impact and just after impact on a backhand drive for six advanced tennis players. The resulting data, from the paper “Forces on the Hand in the Tennis One- Handed Backhand” (International Journal of Sport Biomechanics [1991]: 282–292), are given in the accompanying table. Use the signed-rank test to determine if the mean postimpact force is greater than the mean preimpact force by more than 6.
