An ecology laboratory studied tree dispersion patterns for the sugar maple, whose seeds are dispersed by the wind, and the American beech, whose seeds are dispersed by mammals. In a plot of area \(50 m\) by \(50 m\), they measured distances between like trees, yielding the following distances in meters for 19 American beech trees and 19 sugar maple trees:
(a) Test the null hypothesis that the means are equal against the one-sided alternative that the mean for the distances between beech trees is greater than that between maple trees.
(b) Construct two box plots to confirm your answer.
