Refer to the Evolutionary Ecology Research (July 2003) study of the patterns of extinction in the New Zealand bird population, Exercise 3.28. Of the 132 bird species saved in the NZBIRDS file, 38 are extinct. Suppose you randomly select 10 of the 132 bird species (without replacement) and record the extinct status of each.
a. What is the probability that exactly 5 of the 10 species you select are extinct?
b. What is the probability that at most 1 species is extinct?

Data from Exercise 3.28

Refer to the Evolutionary Ecology Research (July 2003) study of the patterns of extinction in the New Zealand bird population. Consider the data on extinct status (extinct, absent from island, present) for the 132 bird species saved in the NZBIRDS file. The data is summarized in the MINITAB printout reproduced here. Suppose you randomly select 10 of the 132 bird species (without replacement) and record the extinct status of each.
