Researchers determined that 60 Kleenex tissues is the average number of tissues used during a cold. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: x = 52 and s = 22. Suppose the alternative we wanted to test was H.: u < 60 The correct rejection region for a = 0.05 is
