2.125 Extinct New Zealand birds. Refer to the Evolutionary D Ecology Research (July 2003) study of the patterns of ex- NZBIRDS tinction in the New Zealand bird population, first presented in Exercise 2.24 (p. 42). Again, consider the data on the egg length (measured in millimeters) for the 132 bird species. a. Find the 10th percentile for the egg length distribution and interpret its value. b. The moas (P. australis) is a bird species with an egg length of 205 millimeters. Find the z-score for this spe- cies of bird and interpret its value.
