Answer #1

Correct options:

whether or not the sample was randomly selected

the size of the sample compared to the number of students living in dormitories at the university

Explanation:

The conditions for generalization from sample results to overall population:

(1) The sample group must be true representative of the population

(2) the size of the sample must allow the statistics to be safely extrapolated to entire population.A group that is too small may not capture the variation in the broader population.
