Determine whether the sample is biased or unbiased. Explain. You want to estimate the number of people in a town who think that a park needs to be remodeled. You survey every 10th person who enters the park.

Choices:

biased; The sample is not representative of the population because people who go to a park are more likely to think that the park needs to be remodeled.

biased; The sample is representative of the population and selected at random.

unbiased; The sample is representative of the population because people who go to a park are more likely to know the park's needs.

unbiased; The sample is representative of the population, selected at random, and large enough to provide accurate data.
