Question
Transcribed Image Text:A researcher noticed that today's adolescents seem to have higher rates of social anxiety than those of
generations past. In 1990, the average level of social anxiety in adolescents was μ = 15.5. The researcher
collects data by sampling 100 adolescent students from the tristate area and records their level of anxiety.
Testing at an alpha level of a = .05, what will the researcher conclude about today's adolescents?
