Question

Lorena took a survey of the students in her honors science class to determine how many are going to college. She found that 85% of the students plan to go to college.

Can Lorena make the inference that 85% of all the seniors at her school are going to college?

Answer 1

No, Lorena’s sample was biased because it was taken only from an honors class.

No, Lorena’s sample was not a random sample of the entire school.

those are the two correct answers, i took the test!

Answer 2

No, Lorena cannot make the inference about all the seniors going to college.

Explanation:

We are given that Lorena took a survey of students in her science class to determine how many of them were going to college.

From the survey results, she found that 85% of the students from her science class were going to the college but with these results she cannot infer that 85% of all the seniors at her school were going to college.

This is because the survey was biased as it was not taken from the entire school but only Lorena's science class.
