3. A psychologist is studying the effects of lack of sleep on the performance of various perceptual-motor tasks. After a given period of sleep deprivation, a measurement of reaction time to an auditory stimulus was taken for each of 36 adult male subjects. The reaction times (in seconds) are summarized as follows: x = 1.82, s 0.22 = Previous psychological studies show that the true mean reaction time for non-sleep- deprived male subjects is 1.70 seconds. a. Does the sample evidence indicate that the mean reaction time for sleep- deprived male subjects is longer than that of non-sleep-deprived male subjects ? a = 0.05
