Answer 2

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.

What is sample?

" Sample is defined as the small part of the whole data which represents the information about whole data."

According to the question,

Total number of students in art class = 27

Percent of students watching T.V. news from art class = 30%

Statement given by Marlow,

30% of the school's student population would be expected to enjoy watching the TV news.

30% of students of art class sample ≠ 30% of school's student population sample

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