A study is under way in Yosemite National Forest to determine the adult height of American pine trees. Specifically, the study is attempting to determine what factors aid a tree in reaching heights greater than 60 feet tall. It is estimated that the forest contains 25,000 adult American pines. The study involves collecting heights from 250 randomly selected adult American pine trees and analyzing the results. Identify the population from which the study was sampled.

a. the 250 American pine trees from which the data was collected

b. the 25,000 adult American pine trees in the forest

c. all the adult American pine trees taller than 60 feet

d. all American pine trees, of any age, in the forest.

b. the 25,000 adult American pine trees in the forest

Explanation:

Population refers to the total of all the subjects for which the study is done. The study here takes a sample of 250 trees approximately. But the conclusion of study will be applied on entire population under study which is 25,000 pine trees.

As the word population in a study refers to the total number on which the conclusion will be applied. as in the given case if all the samples are above the height of 60 feet, it will be concluded that the entire population of about 25,000 pine trees is above 60 feet.
