Marlow wants to know how many students in his school enjoy watching the TV news. He asks all 27 students in his art class and finds that 30% of his classmates enjoy watching the TV news. He claims that 30% of the school's student population would be expected to enjoy watching the TV news. Is Marlow making a valid inference about his population?

    No, it is not a valid inference because he asked all 27 students in his art class instead of taking a sample from the school No, it is not a valid inference because his classmates do not make up a random sample of the students in the school Yes, it is a valid inference because he asked all 27 students in his art class Yes, it is a valid inference because his classmates make up a random sample of the students in the school

    pretty sure its the last one because there is no reason it wouldn't be invalid.
