Question

If we collect information on students' study practices and exam scores and find strong evidence of a positive association between not studying more than two hours and high grades, when can we generalize this finding to the general population?

Answer 1

A student list for the college was obtained and students were randomly selected from the list to participate.

Step-by-step explanation:

When the we select them randomly based on the test subject population, we can make a safe assumption that those random selection actually represent the real life demographic of the general population. If we select them manually, we will create a risk of biased pick (the selected could have similar characteristics that the researchers personally like)
