How many tissues should the Kimberly Clark Corporation package of Kleenex contain? Researchers determined that the mean number of tissues used during a cold is less than 60 tissues. Suppose a random sample of 100 Kleenex users yielded the following data on the number of tissues used during a cold: X = 52, S = 22. Suppose the test statistic does fall in the critical region at the 0.05 level of significance. At a = 0.05,which of the following conclusions is correct?
