Note:

Hey there! Thank you for the questions. Since you have posted 2 unrelated questions, we have solved one for you, the one with the Gallup poll. If you need help with the other question, please re-post it.

Explanation:

a)

Population: In terms of Statistics, a population is defined as the collection of all individuals possessing a certain characteristic of interest in a study, who may potentially be considered for the study at hand.

The study is conducted to understand the spending patterns, and interest in saving, among the adult Americans. Although the study is conducted on a small section of the population, the conclusion is made on all adult Americans.

Thus, the population of interest is all adult Americans above 18 years of age.

b)

Sample: In terms of Statistics, a sample is a subset or a section of the population of interest, on which, the study is actually performed.

In this case, 1,016 adults are randomly selected from among all adult Americans of all the 50 states of the country, and asked the relevant questions to understand their spending and saving habits.

Hence, the sample consists of the 1,016 randomly selected adult Americans from among all adult Americans in all 50 states.
