PLEASE HELP WILL GIVE BRAINLEST


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

Hello!

Jerome is not making a valid inference. 

Why?

Note that he only asked 28 students from his own class, not a random sample of students from his entire school. Granted, a lot of students may like comedy TV shows, this does not mean that Jerome can correctly assume that exactly 70% of the entire school will like comedy shows. Taking a random sample of many students from different classes can give Jerome a more accurate assumption.

The correct answer is "No, it is not a valid inference because his classmates do not make up a random sample of the students in the school"
