distribution of tree species

An ecologist studied the spatial distribution of tree species in a wooded area. From a total area of 21 acres, he randomly selected 144 quadrats (plots), each 38 feet square, and noted the presence or absence of maples and hickories in each quadrat.The results are shown in the table.18

The value of the chi-square statistic for this contingency table is  . Test the null hypothesis that the two species are distributed independently of each other. Use a nondirectional alternative and let  ∝= 0.01. In stating your conclusion, indicate whether the data suggest attraction between the species or repulsion. Support your interpretation with estimated conditional probabilities from the data.
