question 44

Multiple Choice

How many tissues should the Kimberly Clark Corporation package of Kleenex contain? Researchers determined that 60 tissues is the average 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: $\bar { X }$ = 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: \(\bar { X }\) \(\ge\) 60 and H₁:
• \(\bar { X }\) < 60
• B) H₀: \(\bar { X }\) = 52 and H₁:
• \(\bar { X }\) \(\neq\)52
• C) H₀: \(\mu\) \(\ge\) 60 and H₁: \(\mu\)< 60
• D) H₀: \(\mu\) \(\le\)
• 60 and H₁: \(\mu\)> 60
