A clinical psychologist is investigating the effectiveness of a new therapy technique for reducing symptoms of social anxiety. She randomly assigns participants to either the new therapy group or a traditional therapy group. After 8 weeks of treatment, participants complete a social anxiety assessment (lower scores indicate less anxiety). New Therapy group: 25 participants, mean score = 42, standard deviation = 9.5Traditional Therapy group: 28 participants, mean score = 47, standard deviation = 10.2 Using an alpha level of 0.05, determine if there is a significant difference in the effectiveness of the two therapy techniques in reducing social anxiety symptoms.
