I apologize for the mistake in my previous response. The correct conclusion that can be drawn from the data is: There is more variability in the tennis team member heights.

This can be inferred from the fact that the mean absolute deviation for the tennis team is smaller (1.8 inches) compared to the baseball team (2.44 inches), indicating that the heights of tennis players are less spread out or more consistent than the heights of baseball players.
