Question

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?

Answer 1

no, it is not a valid inference

Explanation:

it is not a valid inference because he only asked the 27 students in his art class instead of taking a sample from the school

Answer 2

No

Explanation:

there are more than 27 kids in the school and without the total number of kids in the school you can't infer a percentage for all of them
