question 93

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. Give the null and alternative hypotheses to determine if the number of tissues used during a cold is less than 60.

• A) H₀: μ ≤ 60 and H₁: μ > 60.
• B) H₀: μ ≥ 60 and H₁: μ < 60.
• C) H₀: X ≥ 60 and H₁: X < 60.
• D) H₀: X = 52 and H₁: X ≠ 52.
