The wing stroke frequencies of two species of Euglossine bees were recorded for a sample of n = 4 Euglossa mandibularis Friese (species 1) and n = 6 Euglossa im- perialis Cockerell (species 2). The frequencies are listed in Table 15.3. Can you con- clude that the distributions of wing strokes differ for these two species? Test using = 0.05.
