Thinking Mathematically (6th Edition)

We can see the following information on the graph: - Blue bars represent the percentage of Americans who prefer men in various jobs. - Yellow bars represent the percentage of Americans who prefer women in various jobs. - The blue bar for elementary school teachers is below the dotted line for $10\%$: less than 10% of Americans prefer men. - The yellow bar for elementary school teachers stops around the dotted line for $60\%$: around $60\%$ of Americans prefer women. A - the set of jobs for which more than $20\%$ prefer men. B - the set of jobs for which more than $20\%$ prefer women. We can see that elementary school teacher is a job that belongs in B but not in A; therefore, it belongs in the $III$ region.
