A researcher studied the impact of sleep deprivation on problem solving. He collected data from a sample of n = 10 students. On the first day of the study, each student attempted to answer 20 logic problems. They were then instructed to not sleep for the next 24 hours. On the next day the students, now sleep deprived, attempted to answer another set of 20 logic problems. The researchers recorded the number of problems each student solved before versus after sleep deprivation. The data are shown here: Student Before After Zachary 16 15 Yolanda 12 13 Xian 16 14 Wayne 13 13 Vera 16 16 Ursula 17 14 Tom 13 12 Siobhan 18 19 Ravi 18 17 Quadim 17 17 1. Calculate D and D². 2.
