Over a period of several years in a sleep-therapy clinic, the average latency to fall asleep for adult males, age 20-30, has been found to be 335 seconds. In a study of the effectiveness of hypnotic therapy, 30 males of the appropriate age are given the treatment and then their latency to fall asleep is measured. The results are a mean latency of 283.7, with a variance of 5,756.26 seconds. Test the hypothesis that hypnotic therapy has no effect on sleep latency. Use an a level of .05 and a nondirectional test. Using the sample information in Exercise 12, determine the 95% and 99% con- fidence intervals for u. war period, the ar program has been found For the inout grade po Jule prop 1 753, with
