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 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.
C) At = 0.05, you reject H0. D) At = 0.05, you do not reject H0.
Question 2
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.
