Question

what percentage of the students in the sample want the mascot to be a tiger?
30 %
if all the students at quinns school vote for their favorite mascot, would you expect exactly 30% of the students to vote for a tiger?
yes. a random sample always has exactly the same characteristics as the population.
no. the results of random samples vary. they are not an exact measure of a population.

Explanation:

A random sample is just a subset of the population. While it can give an estimate of the population's characteristics, it doesn't guarantee that the sample's exact percentage (in this case, 30% wanting the tiger mascot) will match the population's percentage exactly. Random samples can vary from one to another, and they are used to make inferences about the population, not to provide an exact measure.

Answer:

No. The results of random samples vary. They are not an exact measure of a population.
