Question

question 9 of 10
if a population is, a sample of the population could be

a. people who purchased shoes; all customers
b. all citizens; registered voters
c. ninth - graders at peak school; all students at peak school
d. math teachers; the entire school faculty

Explanation:

A population is the entire group of individuals or objects that we are interested in studying. A sample is a subset of the population.

• Option A: “People who purchased shoes” is a subset of “all customers” (if all customers include those who bought other items too). But the order is wrong as the sample should be a part of the population. Here the population (all customers) should be first and sample (people who purchased shoes) second.
• Option B: “All citizens” is the population and “registered voters” (a subset of all citizens) is the sample. This is correct as a sample is a part of the population.
• Option C: “Ninth - graders at Peak School” is a subset of “all students at Peak School”. But the order is wrong. The population (all students at Peak School) should be first and sample (ninth - graders) second.
• Option D: “Math teachers” is a subset of “the entire school faculty”. But the order is wrong. The population (the entire school faculty) should be first and sample (math teachers) second.

Answer:

B. all citizens; registered voters
