    In forestry there appears to be a correlation between the diameter of a tree at breast height and the total height of the tree. For the following sample of ten white spruces, first construct a scatter plot then find the correlation (r) between height, r squared, and T.

    Diameter(cm) Height
    18.9 20.0
    15.5 16.8
    19.4 20.2
    20.0 20.0
    29.8 20.2
    19.8 18.0
    20.3 17.8
    20.0 19.2
    22.0 22.3
    16.6 18.8
