Answer 1

HELP

Answer 2

HELLO

Answer 3

He is making a valid inference because he is Sampling, which is instead of taking the entire school and counting each individual person, he is taking a small sample and amplifying it to fit the entire school. It's a common technique most Scientists use to get the population density of an entire area without counting the absolute entire area

Answer 11

I'm 89% sure, His classmates do make a random sample of students and it really would not differ if they were in his math class, I'm guessing at that grade level they would all be in the same classes, no matter what the time they are all in those classes and did not choose to enroll specifically in History, so yes, it is a random sample of students
