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: = 52, S = 22. Suppose the alternative you wanted to test was H1 : μ < 60. State the correct rejection region for α = 0.05. a. Reject H0 if t > 1.9842 or Z < -1.9842. b. Reject H0 if t < -1.9842. c. Reject H0 if t > 1.6604. d. Reject H0 if t < -1.6604.
