Explanation:

First Question (Population)

The population in a survey is the entire group we want to study. Here, we aim to study U.S. adults' feelings of being well - rested, so the population is the responses of all U.S. adults. Option A matches this. Option B is a percentage of the population, not the population itself. Option C is the sample, not the population. Option D is a percentage of the sample, not the population.

The sample is the subset of the population that is actually surveyed. In this case, 1001 U.S. adults were selected to be surveyed, so the sample is these 1001 U.S. adults. Option A is the population. Option B is a percentage of the sample, not the sample. Option C is a percentage of the population, not the sample. Option D correctly identifies the sample.

Answer:

A. The responses of all U.S. adults
