Suppose that a biologist studying cuckoo birds knows that the average cuckoo bird weight in the United States is 1.32 pounds. The biologist travels to study the cuckoo birds that live in Timbuktu. Because of the desert heat in Timbuktu, the biologist believes that the birds there will be smaller, and he wants to conduct a hypothesis test using a p-value to test this belief and using alpha =0.8 as his significance level. When the biologist arrives in Timbuktu, he collects a random sample of 36 birds and finds that the weight of the cuckoos in his sample is 1.2 pounds. Suppose that it is known that the standard deviation of cuckoo bird weight in Timbuktu is 0.8 pounds. What is population from which the sample is drawn?

a. All cuckoo birds.
b. All cuckoo birds in the U. S
c. All cuckoo birds in Timbuktu.
