Tennis elbow is thought to be aggravated by the impact experienced when hitting the ball. The article 'Forces on the Hand in the Tennis One-Handed Backhand" (international Journal of Sport Biomechanics [1991]: 282-292) reported the force (N) on the hand just after impact on a one-handed backhand drive for six advanced players and for eight intermediate players. Summitry statistics from the article, as well as data consistent with these summary quantities, appear in the table at the top of the page.

The authors of the article assumed in their analysis of the data that both force distributions (advanced and intermediate) were normal. Use the given information to determine whether the mean force after impact is greater for advanced tennis players than it is for intermediate players.
