Jerome wants to know how many students in his school enjoy watching comedy programs on TV. He poses this question to all 28 students in his math class and finds that 70% of his classmates enjoy watching comedy programs on TV. He claims that 70% of the school's student population would be expected to enjoy watching comedy programs on TV. Is Jerome making a valid inference about this population?

    Yes, it is a valid inference because his classmates make up a random sample of the students in the school Yes, it is a valid inference because he asked all 28 students in his math class No, it is not a valid inference because his classmates do not make up a random sample of the students in the school No, it is not a valid inference because he asked all 28 students in his math class instead of taking a sample from his science class

    A It is not a valid sample because it is only a short study. It is a valid sample because money is offered to participants. It is a valid sample because the first 10 people were selected to participate. It is not a valid sample because it is not a random sample of the population
