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

I think maybe C or A because we dont know how many students there were total.

Answer 1

C because the students were not pulled at random

Answer 2

C. The 25 students don't make up a random sample. She asked a certain group of people when she should have wrote names down and pulled them from a hat and ran a simulation to get the best inference.
