Answer: D) all American school teachers.
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.
A sample is a subset of population that represents the entire population in research.
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.
Based on the formula given of 27π = πn, we can find the value of n after substitution in an equation to be 27.
<h3>What is the value of n?</h3>
The value of n can be found by making n the subject of the formula as shown below;
27π = πn
n = 27π / π
Solving of n therefore gives:
n = 27π/π
n = 27
In conclusion, n is 27.
