A sample of 16 males participated in a sleep experiment in which the percentage of each participant's total sleeping time spent in a certain stage of sleep was recorded. The variance computed from the sample data was 2.25. The 95 percent confidence interval for standard deviation of sleeping time is: O(1.108, 2.322) ) (1.133, 2.218)
