Answer 1

Answer:

Population: All adults in the country

Sample:  The 1,003 adults selected

Step-by-step explanation:

The sample always is a little part of the whole population. This part is the one that you are going use to study and make all the calculations (Example:average, median, percentage, standard deviation).

In that way, the sample represents all the population but is not the population, it's just a part.
