Hummingbirds of Saint Lucia. Eulampis jugularis is a type of hummingbird that lives in the forest preserves of the Caribbean island of Saint Lucia. The males and the females of this species have bills that are shaped somewhat differently. Researchers who study these birds thought that the bill shape might be related to the shape of the flowers that they visit for food.
The researchers observed 49 females and 21 males. Of the females, 20 visited the flowers of Heliconia bihai, while none of the males visited these flowers. Display the data in a two-way table and perform the chi-square test. Summarize the results and give a brief statement of your conclusion. Your two-way table has a count of zero in one cell. Does this invalidate your significance test? Explain why or why not.
