Do teenage boys worry more than teenage girls? This is one of the questions addressed by the authors of the article “The Relationship of Self-Esteem and Attributional Style to Young People’s Worries” (Journal of Psychology [1987]: 207–215). A scale called the Worries Scale was administered to a group of teenagers, and the results are summarized in the accompanying table.

Is there sufficient evidence to conclude that teenage boys score higher on the Worries Scale than teenage girls? Use a significance level of α = .05.
