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:
