Cuckoos lay their eggs in the nests of other host birds. The host birds adopt and then later hatch the eggs. The Eggs workbook contains data on the lengths of eggs found in the nest of host birds. One theory holds that cuckoos lay their eggs in the nests of a particular host species and that they mate within a defined territory. If true, this would cause a geographical subspecies of cuckoos to develop and natural selection would ensure the survival of cuckoos most fitted to lay eggs that would be adopted by a particular host. If cuckoo eggs differed in length between hosts, this would lend

The Eggs workbook contains data on the lengths of eggs found in the nest of host birds. One theory holds that cuckoos lay their eggs in the nests of a particular host species and that they mate within a defined territory. If true, this would cause a geographical subspecies of cuckoos to develop and natural selection would ensure the survival of cuckoos most fitted to lay eggs that would be adopted by a particular host. If cuckoo eggs differed in length between hosts, this would lend some weight to that hypothesis. You’ve been asked to compare the length of the eggs placed in the different nests of the host birds. a. Open the Eggs workbook from the Chapter10 folder and save it as Eggs ANOVA. b. Perform a one-way ANOVA on the egg lengths for the six species. Is there evidence that the egg lengths differ between the species? c. Create a boxplot of the egg lengths. d. Analyze the pairwise differences between the species by creating a means matrix. Use the Bonferroni correction on the p values. What, if any, differences do you see between the species? e. Save your changes to the workbook and write a report summarizing your observations.
