Question

Stanley wants to know how many students in his school enjoy watching talk shows on TV. He asks this question to all 24 students in his history class and finds that 55% of his classmates enjoy watching talk shows on TV. He claims that 55% of the school's student population would be expected to enjoy watching talk shows on TV. Is Stanley making a valid inference about his population? No, it is not a valid inference because he asked all 24 students in his history class instead of taking a sample from 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 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 24 students in his history class

Answer 2

The 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.

Explanation:

You cannot make a valid inference of the preference of watching TV talk shows by only considering students in one class. You have to randomly select people from the whole population (i.e the total number of students in the school) and then make an inference.
