Example Question #1 : Use Data From A Random Sample To Draw Inferences About A Population: Ccss.Math.Content.7.Sp.A.2
The owner of a zoo wants to find out which animal exhibit is the most popular. The owner decided to take a random sample of the zoo's visitors to find out which exhibit was the visitor's favorite. Out of the visitors of the zoo last Friday, the owner asked visitors which exhibit was their favorite. The results are shown in the provided table.
What inference can be made based on the results shown in the provided table?
The zoo could get rid of the Fish Exhibit with the least amount of upset visitors
No inference can be made based on this data
The zoo could get rid of the Panda Exhibit with the least amount of upset visitors
The zoo could get rid of the Polar Bear Exhibit with the least amount of upset visitors
The zoo could get rid of the Fish Exhibit with the least amount of upset visitors
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.
Example Question #1 : Use Data From A Random Sample To Draw Inferences About A Population: Ccss.Math.Content.7.Sp.A.2
School elections are at the end of next week, and there are three students running for class president: Sara, Matt, and Joseph. The school principal decided to take a random sample of students and find out which candidate each student planned to vote into the role of class president.

Example Question #11 : Statistics & Probability
School elections are at the end of next week, and there are three students running for class president: Sara, Matt, and Joseph. The school principal decided to take a random sample of students and find out which candidate each student planned to vote into the role of class president. Out of the students that attend the school, she asked students how they planned to vote. The results are shown in the provided table.
What inference can be made based on the results shown in the provided table?
Other than Sara, Joseph has the best chance of winning
Other than Matt, Joseph has the best chance of winning
No inference can be made based on this data
Other than Sara, Matt has the best chance of winning
Other than Sara, Matt has the best chance of winning
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 which two candidates will likely win the class election. Sara received the most votes out of the principal's pole, followed by Matt; thus, we can infer—based on these results—that Sara and Matt have the best chance to be the future student body class president.
