He compared the respiration rates (per minute) of participants after they had each been in a warm for 15 minutes and then in a cool room for 15 minutes. He reported his results as follows: Mwarm = 20, Mcool = 13, t(44) = 4.76, p < .001. 1. How many participants were in the study? 2. What did Dr. Cy conclude about the effectiveness of relaxing in a warm or cool room?can you help me with D E?
