) A group of researchers wants to assess whether more sleep improves reaction times the next day. One hundred subjects were sent to bed at staggered times between 1 and 10 hours prior to the scheduled common wakeup time, and the time at which each subject fell asleep was noted using EEG electrodes. At a common wakeup time, all subjects were awoken and given a series of reaction-time tests. Subjects' mean reaction times were then analyzed with respect to the duration of their sleep session, and when plotted on a scatter plot seem to be roughly linearly distributed. What is the most appropriate statistical test to use to analyze these data
