Question

There are two types of sneetches, the star-bellied sneetch (S. astra) and the plain sneetch (S. simplex). Professor O. B. Servant counted sightings of these sneetches, identified each sneetch he saw, and classified their location into the three types: Ground, Tree, and Lake. The number of sightings are shown in the table below:

	S. astra	S. simplex
Ground	102	79
Tree	71	66
Lake	81	81

Professor O. B. Servant would like to know if there is a difference in habitat use between the two types of sneetches.
