Scenario 2: Researchers are interested in testing the relationship between authority and compliance. They recruit 20 participants, and have 10 complete a series of instructions given by an authority figure (adult in white lab coat wearing glasses), whereas the other 10 participants complete tasks from a non-authority figure (adult wearing a t-shirt and shorts). The instructions given to participants asked them to complete silly tasks like hopping on one foot, touching one's nose with their tongue, and ironically dabbing, etc. Researchers think that participants will complete more tasks when asked by an authority figure. 1.

If researchers wanted to test their null hypothesis which test would be best? a. Correlation (r) b. Single sample t-test c. Within groups t-test d. Between groups t-test 5. If there were 20 total participants in this study, and 10 participants are in each group, what are the degrees of freedom? 6. What is the critical value?
