Imagine a researcher asks a sample of five people to drive two types of cars and rate each of them on a scale of 1 to 25. The researcher wants to know: Is there is a difference in the ratings of the two types of cars. Below are the data collected: Type A: 20, 10, 11, 23, 7 Type B: 10, 11, 4, 12, 1   Conduct a 2 sample T test using jamovi. Use α = .05. Is the assumption(s) met?  What do you conclude? Present your answer in APA.
