Carla wants to know how many students in her school enjoy watching reality TV shows. She asks all 22 students in her science class and finds that 40% of her classmates enjoy watching reality TV shows. She claims that 40% of the school's student population would be expected to enjoy watching reality TV shows. Is Carla making a valid inference about her population?

about her population? 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 22 students in her science class instead of taking a sample of the students in her school Yes, it is a valid inference because she asked all 22 students in her science class Yes, it is a valid inference because her classmates make up a random sample of the students in the school
