Question

Different varieties of the tropical flower Heliconia are fertilized by different species of hummingbirds. Over time, the lengths of the flowers and the form of the hummingbirds' beaks have evolved to match each other. Here are data on the lengths in millimeters of three varieties of these flowers on the island of Dominica. data301.dat

The data is organized below by the variety, length. then this repeats every two. This may need to be put in to a chart in order to make sense. PLEASE PAY ATTENTION TO SIG FIGS. I tried this question already and it hasn't been filled out all the way.

F =
P =

flower type n s H. bihai ? ? ? ? H. caribaea red ? ? ? ? H. caribaea yellow ? ? ? ?

Explanation / Answer

Results are as follows from where F=310.08 and p=0.000

We reject the null hypothesis of no difference and conclude that mean lengths of the flowers for the three species are significantly different

Flower Type n xbar s s_xbar bihai 16 47.6363 1.286 0.321 red 23 40.3300 1.565 0.326 yellow 15 36.0860 0.821 0.212
