3. A social worker is interested in examining how people who have higher levels of psychological resiliency respond after a natural disaster. She obtained anxiety scores, which were measured on a scale of 1-12 with higher numbers meaning more anxiety, from eight individuals who had experienced a natural disaster. She collected these scores 3 weeks after the disaster (M=8.63) and 6 months after the disaster (M=4.38). She expected that the anxiety scores at 6 months would be much lower than at 3 weeks. If sD = 1.16 and you use a two-tailed test with an alpha of .05, is there a difference? Perform the 4 steps of hypothesis testing. %3D Anxiety at 3 Anxiety at 6 weeks months 12 7 10 4 11 7 4 7 8. 6215
