You Want to Compare Prices of Textbooks, So You Ask

Short Answer

You want to compare prices of textbooks, so you ask six friends who are science majors and six friends who are humanities majors to report how much they spent on textbooks this term.
-Sketch what this graph would look like if it's not the case that all science majors spent more than all humanities majors, but there is a tendency for science majors to spend more than humanities majors on textbooks.
