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

The null hypothesis should state that the mean number of tissues used during a cold is equal to or greater than 60 (μ ≥ 60). The alternative hypothesis should state that the mean number of tissues used during a cold is less than 60 (μ < 60). Therefore, the correct null and alternative hypotheses are H₀: μ ≥ 60 and H₁: μ < 60, which are only present in choice C.
