Please help me out with this one

5. An old, time-honored study in psychology was conducted by Jenkins and Dallenbach (1924). They had students memorize a list of nonsense syllables, then followed the learning by 8 hours of sleep or 8 hours of waking activity, and finally tested the students to see how much of the original learning was retained. They found that far less forgetting occurred after sleep than after waking activity. Scores for the Awake List Scores for the Sleep List 6 4 11 4 6 6 5 7 5 9 8 9 6 8 10 11 10 10 3 7 A. A research hypothesis is a statement of how you expect the study to turn out. Based on Jenkins and Dallenbach's results of 70 years ago, what is our research hypothesis? B. Calculate the mean for number of words recalled after eight hours awake and the mean for number of words recalled after eight hours asleep. C. Calculate the variance for the awake group using the defining method and the variance for the asleep group using the computational method. D. Calculate the standard deviations for both groups. E. Is the hypothesis supported--does there seem to be a difference in retention after sleep and after waking activity? F. What are the independent and dependent variables in this study? G. What variables could confound our results
