5. Graphs, at last! Now construct histograms of the 200 z values and the 200 t values. These two graphical displays will provide insight about how each of these two statistics behaves in repeated sampling. Use the same scale for the two histograms so that it will be easier to compare the two distributions.
Graph → Histogram In the “Graph variables” box, enter c10 for graph 1 and c11 for graph 2 Click the Frame dropdown menu and select multiple graphs.
Then under the scale choices, select “Same X and same Y.”
