Three varieties of flowers. The study of tropical flowers
Chapter , Problem 1.153(choose chapter or problem)
Three varieties of flowers. The study of tropical flowers and their hummingbird pollinators (Exercise 1.88, page 52) measured the lengths of three varieties of Heliconia flowers. We expect that such biological measurements will have roughly Normal distributions. (a) Make Normal quantile plots for each of the three flower varieties. Which distribution is closest to Normal? (b) The other two distributions show the same kind of mild deviation from Normality. In what way are these distributions non-Normal? (c) Compute the mean for each variety. For each flower, subtract the mean for its variety. Make a single data set for all varieties that contains the deviations from themeans. Use this data set to create a Normal quantile plot.Examine the plot and summarize your conclusions.
