Question

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.

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 ? α = 0.05

(iii) The p-value for the above problem is
