A clinical psychologist is investigating the relationship between sleep and feelings of anxiety. For a sample of 15 individuals, he asks each participant to indicate how many hours they typically sleep each night and each participant also completes an anxiety assessment. The following data is obtained: Hours of sleep: M=6.0 SS=16.0 Anxiety scores: M=8.0 SS=64.0 SP = - 20.0 d. Conduct a hypothesis test using an alpha level of α = .01 to determine if the correlation is significant. Include all steps.
