Cardigan and Connor (1994) examined the foraging behavior of a parasitoid wasp, Closterocerus tricintus, that attacks the leaf-mining moth Cameraria hamadryadella. They sampled seven white oak trees and determined the average density of leaf-mines caused by C. hamadryadella on randomly chosen leaves for each tree. They also recorded the average density of leaf-mines on leaves which they observed C. tricinctus to visit on each tree. Test the hypothesis that C. tricinctus chooses to visit leaves with leaf-mine densities that are higher than the average density of leaf-mines on these

trees. State your null and alternative hypothesis, perform and report the details of the test and interpret the results. See attached data file.
