"Conservationists have despaired over destruction of tropical rain forest by logging, clearing, and burning." These words begin a report on a statistical study of the effects of logging in Borneo. Here are data on the number of tree species in 12 unlogged forest plots and 9 similar plots logged 8 years earlier: Unlogged Logged 22 18 22 20 15 21 13 13 19 13 19 15 17 4 18 14 18 15 15 10 12 Does logging significantly reduce the mean number of species in a plot?
