It is thought that exercising early in the morning will provide better energy throughout the day. To test this idea, subjects are recruited and randomly assigned to two groups: For 30 days, members of the experimental group will walk from 7:00 to 7:30 a.m., Monday through Friday; members of the control group will do no walking. At the conclusion of the study, each subject will answer the 10 questions on the Acme End-of-the-Day Energy Scale. This instrument produces a score between 1 and 100 (1 = extremely low energy, 100 = extremely high energy).
Data set: Ch 05 – Exercise 08A.sav Codebook Variable: group Definition: Walking group assignment Type: Categorical (1 = No walking, 2 = Walking: 30 minutes) Variable: energy Definition: Energy level Type: Continuous (1 = extremely low energy, 100 = extremely high energy)
1. Write the hypotheses.
2. Run each criterion of the pretest checklist (normality, homogeneity of variance, and n) and discuss your findings.
3. Run the t test and document your findings (ns, means, and significance [p value]).
4. Write an abstract up to 200 words detailing a summary of the study, the t test results, hypothesis resolution, and implications of your findings.
