in a data or a word problem for example .... Paul reports that one out of every five boys on the boysâ€™ varsity basketball team can dunk a
basketball after he conducts a survey of the boys on the team.

If someone conducts a survey of a group of people among a larger population then it would be a SAMPLE.

But if the survey includes EVERYONE in the population then it's a population.

For instance, if I want to know the approximate percentage of people who smoke in my town of 500,000 people, it would be really hard to knock on every door and ask if they smoke. Instead, I would take a random sample of maybe 100 households and make a survey of them because they represent typical homes in my town. That would be a SAMPLE.

wait so for ....After examining eight cartons of eggs at a local supermarket, Sheila concludes that one out of
every 12 eggs packaged in the U.S. is cracked. would it be a population and for....Jorge surveys each of the teachers in his school. He concludes that 64% of the teachers in his
school enjoy reading as a hobby.a sample

Just the reverse. Sheila conducted a SAMPLE survey because she only examined eight cartons in ONE supermarket. The population of egg cartons in the US is MILLIONS. So she only conducted a small sample.

Jorge, on the other hand, surveyed ALL the teachers in his school. So he conducted a population survey.

yes so because shelia only conducted her data from a smaller portion of the whole thing its a sample and because jorge conducted his data from all the teachers and his data uses the whole population its a population.
