I would like help with question 2 both A and B. **Transcription for Educational Website:**---**Study on Cognitive Behavioral Therapy (CBT) for Stress Reduction**A psychologist implemented a treatment method known as Cognitive Behavioral Therapy (CBT) to assist college students in managing stress. This method involved weekly therapy sessions for a group of 30 students. The stress levels of these students were assessed before the commencement of the first session and after the conclusion of the final session. The objective was to quantify the stress reduction attributed to the CBT intervention.**Stress Measurement Details:**- **Initial Average Stress Score (M1):** 35- **Post-Therapy Average Stress Score (M2):** 29.5- **Mean Difference in Stress Scores (MD):** 5.5- **Sum of Squares of Differences (SS):** 426.3Using this data set, the psychologist aims to achieve the following:**a. Point Estimate of Mean Difference:**- Compute a point estimate for the mean difference in stress scores between the two measurements (initial and final sessions) across the population of interest.**b. Confidence Interval for Mean Difference:**- Determine an interval estimate to ensure there is 90% confidence that the true population mean difference falls within this interval.---This analysis serves as a basis for understanding the effectiveness of CBT in reducing stress among college students, providing insights into potential psychological interventions for stress management.
