Refer to the Journal of Biogeography (December 2003) study of ants in Mongolia (central Asia), presented in Exercise. Recall that botanists placed seed baits at 11 study sites and observed the number of ant species attracted to each site.

A portion of the data (saved in the GOBIANTS file) is provided in the next table (p. 380). Do these data indicate that the average number of ant species at Mongolian desert sites differs from 5? Conduct the appropriate test at α = .05. Are the conditions required for a valid test satisfied?
