Theo would like to estimate the mean number of vehicles each person owns in his town. The town has a population of 12,000 people. Which statements are true?

Select each correct answer.

To estimate the mean number of vehicles owned using a sample, Theo needs to randomly select the people he will survey so that his sample represents the population well.

An estimate can only be made by surveying all 12,000 people in the town.

The larger the number of people Theo surveys, the better his estimation of the mean will be.

If Theo collects a sample of people at the car dealership and surveys them, he can use that data to estimate the mean number of vehicles each person owns in his town.
