Mateo is an editor for a publishing company that prints short stories and academic articles. Last month,
Mateo kept track of the number of pages that were
in each article or short story he edited and the
number of typos he found in each. Below is a scatter
plot showing the relationship between the number of
pages and the number of typos.

Do Mateo's data show a positive association or a
negative association? Explain how you know.
