The sample is the 50 conference attendees, and the population is all teachers in the state.

Step-by-step explanation:

The 50 conference attendees are asked (sampled) and this is used to get an ideia about the population, that is all the teachers in the state.

This is a normal practice of sampling.

For example, if you wanted to know what percentage of New York State residents are Buffalo Bills fans, you would ask a sample, like of 500 residents, and then use this to have an ideia about the entire population.

So the correct answer is:

The sample is the 50 conference attendees, and the population is all teachers in the state.
