In order to answer this question we first need to know what "sample" means. A sample is a subset of a population. 

Because we want a subset, we don't want the entire population, which eliminates the answer choices "Every person who saw the movie" and "Every person in the United States old enough to see the movie". The question did not specify if the director wanted just the boys' opinions, which makes  "A random selection of people who saw the movie" the best answer choice. 

In order to answer this question we first need to know what "population" means. A population is the entire group that is being studied. In this case, people of Washington. 

Because the barbecue company is only concerned about what the people in Washington thinks of their new barbecue flavor, we can eliminate the option for everyone in the United States, because we are focused on only one state. Also, a population includes both adults and children, which is why "Every person in Washington" is the best answer choice. 

In order to answer this question, we first need to know what "population" means. A population is the entire group that is being studied. In this case, it's all of the kids in the United States.  

Because the eye glasses company is only concerned about what kids think of their new style, we can eliminate all of the options that say "everyone" or "every adult", leaving us with "Every child in the United states" as our correct answer. 

In order to answer this question we first need to know what "population" means. A population is the entire group that is being studied, in this case all of the customers the shop at the grocery store.

"The entire population in the United States" and "The entire population in California" are not the correct answer because not everyone in an entire population shops at the same grocery store, and this store is only concerned about their own customers. Also, a random sample does not represent a population, so that is not the correct answer. 

In order to answer this question we first need to know what "population" means. A population is the entire group that is being studied, in this case all of the customers the shop at the clothing store. 

"The entire population in the United States" and "The entire population in Indiana" are not the correct answer because not everyone in an entire population shops at the same clothing store, and this store is only concerned about their own customers. Also, a random sample does not represent a population, so that is not the correct answer. 

In order to answer this question we first need to know what "sample" means. A sample is a subset of a population. 

Because we want a subset, we don't want the entire population, which eliminates the answer choices "Everyone who was at the debate ". Also, the principal wants to know what the student body thought about the topics debated, not the teachers, which eliminates "All of the teachers". Finally, the principal didn't specify if she wanted just the girls' opinions, which makes "A random sample of the students who were at the debate" the best answer choice. 

In order to answer this question we first need to know what "sample" means. A sample is a subset of a population. 

Because we want a subset, we don't want the entire population, which eliminates the answer choice "Everyone who was at the choir concert ". Also, the teacher wants to know what the student body thought about the songs, not the teachers, which eliminates "All of the teachers". Finally, the music teacher didn't specify if she wanted just the girls' opinions, which makes "A random sample of the students who were at the concert" the best answer choice. 

We can use data from a random sample to make inferences about a population. In this case, our population is all of the visitors of the zoo on Friday, and the random sample is the  visitors that were randomly selected by the owner and asked which exhibit was their favorite.

Based on our answer choices, we are making an inference about which animal exhibit the zoo could get rid of with the least amount of upset visitors. The fish received the least votes out of the owner's pole; thus, we can infer—based on these results—that the least amount of people will be upset if the zoo got ride of the Fish Exhibit. 

We can use data from a random sample to make inferences about a population. In this case, our population is the entire student body, and the random sample is the  students that were randomly selected by the principal and asked how they planned to vote. 

Based on our answer choices, we are making an inference about who will likely win the class election. Sara received the most votes out of the principal's pole; thus, we can infer—based on these results—that Sara will be the future student body class president.

We can use data from a random sample to make inferences about a population. In this case, our population is the entire student body, and the random sample is the  students that were randomly selected by the principal and asked how they planned to vote. 

Based on our answer choices, we are making an inference about who will likely place third in the class election. Joseph received the least votes out of the principal's pole; thus, we can infer—based on these results—that Joseph will place third.
