Question

(08.01)Maggie wants to know how many students in her school enjoy watching sports on TV. She asks all 25 students in her math class and finds that 60% of her classmates enjoy watching sports on TV. She claims that 60% of the school's student population would be expected to enjoy watching sports on TV. Is Maggie making a valid inference about her population?

Yes, it is a valid inference because she asked all 25 students in her math class

Yes, it is a valid inference because her classmates make up a random sample of the students in the school

No, it is not a valid inference because her classmates do not make up a random sample of the students in the school

No, it is not a valid inference because she asked all 25 students in her math class instead of taking a sample from her geography class

Answer 1

Yes, because her class represents a random sample of students in the school

Step-by-step explanation:

Answer 2

Yes, because her class represents a random sample of students in the school. Instead of asking every single student in the school, which would take too long, it is much easier to poll a small group of people to see what they think, and then have their opinion represent a larger community. Although if Maggie had asked more people, her answer would have been more precise, the sample could still be highly accurate. Hope this helps even though I am asking the day after this was posted and this question is in the wrong subject. It should be in math, but it's not that big of a deal.
