3. A researcher suspects that the actual prevalence of generalızed anxlet adolescents is higher than the previously reported prevalence of generalized anxiety disorder among children and adolescents. The previously reported prevalence of generalized anxiety disorder among children and adolescents is 3.9%, and the researcher conducts a study to test the accuracy of the previously reported prevalence of generalized anxiety disorder by recruiting 98 children and adolescents from various pediatricians' offices and tests them for generalized anxiety disorder using the DSM-5. The researcher determines that the prevalence of generalized anxiety disorder among the participants of the study is 6.1%. For a level of significance of 5%, what should the researcher's decision rule look like? A) Reject Ho if z is less than or equal to -1.645. B) Reject Ho if z is greater than or equal to 1.645. C) Reject Ho if z is less than or equat to -1.96. D) Reject Ho if z is greater than or equal to 1.96. HO
