if a population consist of 320,000 people, a sample of the population could consist of which of the following numbers of people.
a- 32,000
b-32,000,000
c-320,000,000
d-3,200,000

a)32000

Step-by-step explanation:

A sample of a population is a subset of said population, therefore, the sample is smaller than the total population.

We observe that the options given in B), C), D) are all bigger than 320,000, therefore they can't be samples of this population.

On the other hand 32,000 < 320,000 and this is a choice for a sample.
