4. Sleep Deprivation: (10 pts) Sleep researchers decide to test the impact of REM sleep deprivation on a computerized assembly line task Subjects are required to participate in two nights of testing in which subjects are allorwed a total of four hours of sleep each night However, on one of the nights, the subject is awakened immediately upon achieving REM sleep (REM deprived. On the altenate night, subjects are randomly awakened at various times throughout the hou total sleep session (Control). Each subject, after the sleep session, is required to complete a computerized assembly line task. The task involres five rows of widgets slowly passing across the computer screen Randomly placed on a one five ratio are widgets missing a component that must be fixed" by the subject. Number of missed widgets is recorded and presented below. Conduct a ttailed paired sasples t-test by hand using an alpha level of.05 to determine whether sleep deprivation affects performance on the assembly line task Record your answers below.
