Step-by-step explanation:
In statistics, A population is a very large set of individuals or values that belong to a specified group established by researcher.

Given : We want to know the opinions of American school teachers about establishing a national test for high school graduation.
Clearly , by the above definition
Population = all American school teachers.
You obtain a list of the members of the National Education Association and mail a questionnaire to 2500 teachers chosen at random from this list.
sample = 2500 teachers chosen at random from this list.
Hence, the intended population is all American school teachers.
Thus , the correct answer is D) all American school teachers.
