2. 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 humming- birds' beaks have evolved to match each other. Here are data on the lengths (mm) of three randomly selected varieties of these flowers on the island of Dominica. You can assume that these random samples are from normally distributed populations with equal variances. H. bihai T = 761.56 n=16 H. caribaea red H. caribaea yellow Tr. = 796.49 n = 20 T. =542.70 ny=1 = 15 , = 87696.38 [6] Is there any overall variability on the lengths of Heliconia flowers?
