A study looked at the consequences of sleep deprivation on a sample of thousands of medical school interns. Some programs offered night-float coverage, the assignment of another physician to take calls for the on-call participant during an overnight shift for a period of time so that the participant could rest. The average number of sleep hours per extended shift for those with night-float coverage was significantly greater than the number for those without night-float coverage (3.1 ±1.6 hours vs. 2.4 ± 1.7 hours; t = 21.3; P < 0.001).
What was the difference in sample mean hours of sleep for the two groups?
The sample mean of 1st group is 3.1 hrs and that of 2nd group is 2.4 hours. Hence the difference between two groups is 0.7Hrs. Which is basically 42 mins. The statistic is represented by mean and the error confidence term.
Thanks

Dr. Snooze looked at the effect of sleep deprivation on cognitive functioning in elderly men and women. He contacted local doctors specializing in geriatrics to obtain a sample for this study. On Monday morning at 8:00 am after 8 hours of sleep the night before, and then again a week later at 8:00 am after 4 hours of sleep the night before, 35 subjects solved a complicated maze when they arrived at the lab in the morning and the time...
