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. Bellow are the data collected: Type A: 20, 10, 11, 23, 7 Type B: 10, 11, 4, 12, 1 Based on available info the significance level is a= 0.5 and the degree of freedom = 4 3. What do you conclude? Present your answer in APA ------------------- NB* I have attached my work solving up to this point. Please help me answer Based on your conclusion identify and explain the type of error you could be making.
