1. Nancy questioned 21 students who were all in the same introductory math class at her college. 2. In the dark Jamie picked out t-shirts from her closet.

Are these biased or non-biased

If I'm right>  (brainliest plz)

if I'm wrong --->(SORRY)

Step-by-step explanation:

i would say A. a convenience sample that is not representative of all first-year college students. there are more than 20 first-year college students in the world so obviously only talking to 20 of them won't be representative of /everyone/

and the convenience is that she only handed them out to people in the library; where she spends most of her time, therefore making it more convenient for her.
