Answer:

Sample: few thousand adults

Population: all the adults

Step-by-step explanation:

A sample is a subset of the population, selected randomly.

In this case:

The sample consist of the few thousand adults selected to determine the opinions about the National polls.

The population consist of all the adults belonging to the said nation.

Consider an example about the new President election.

To determine which of the two candidates (say <em>A</em> and <em>B</em>) has a higher probability of winning the President election, the election society took a random sample of voters and asked who they think will be a better president.

The sample selected will be large enough, probably 10% of the population of all voters.

From this study it can be estimated which candidate has the higher chance of winning.
