You may only be given one of these values (the critical value or the significance level), so you should know how to use both. Dividing up space: coordinate geometry, lines, Voronoi diagrams Remember to write down the null and alternative hypotheses. 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.
