How Many Tissues Should the Kimberly Clark Corporation Package of Kleenex

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.
