question 37

Multiple Choice

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: μ < 60. State the correct rejection region for α = 0.05.

• A) Reject H₀ if t > 1.6604.
• B) Reject H₀ if t < -1.6604.
• C) Reject H₀ if t > 1.9842 or Z < -1.9842.
• D) Reject H₀ if t < -1.9842.
