Developing inquiry skills Let the measurement of the largest height of the trees in the opening problem be h. Divide the trees into small, medium and large, where small trees have h < 4.5 ill, medium, 4.5 < h < 5.0 m, and large h> 5.0 m. Use these categories to form a contingency table for the trees in areas A and B, and test at the 5% significance level whether the heights of the trees are independent of the forest area they were taken from.
