Do a post hoc comparisons, comparing the 48-hour sleep-deprived group and the normal sleep group using the Tukey HSD test. What do you conclude? Compare your answers to parts e and f. Explain any difference. g. Same as part f, but use the Scheffe test.A sleep researcher conducts an experiment to determine whether sleep loss affects the ability to maintain sustained attention. Fifteen individuals are randomly divided into the following three groups of ve subjects each: group 1, which gets the normal amount of sleep (778 hours); group 2, which is sleepdeprived for 24 hours; and group 3, which is sleepdeprived for 48 hours. All three groups are tested on the same auditory vigilance task. Subjects are presented with half-second tones spaced at irregular intervals over a l-hour duration. Occasionally, one of the tones is slightly shorter than the rest. The subject's task is to detect the shorter tones. Note: These data are not exactly the same as in the textbook.
