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 rejection region at  = 0.05. Which of the following decisions is correct?
 
  A) At  = 0.10, you reject H0. B) At  = 0.10, you do not reject H0.

How many tissues should the Kimberly Clark Corporation package of Kleenex contain? Researchers determined that 60 tissues is the mean 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, S = 22. Suppose the alternative you wanted to test was H1 :  < 60. State the correct rejection region for  = 0.05.
 
  A) Reject H0 if t < -1.6604. B) Reject H0 if t > 1.9842 or Z < -1.9842.
  C) Reject H0 if t > 1.6604. D) Reject H0 if t < -1.9842.
