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.

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 sp = 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.
