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: ? $\le$ 60 and H₁: ? $\gt$ 60. B)H₀: ? $\ge$ 60 and H₁: ? $\lt$ 60. C)H₀: x? $\ge$ 60 and H₁: X $\lt$ 60. D)H₀: X = 52 and H₁: x? $\neq$52.

The null hypothesis should state that the mean number of tissues used during a cold is greater than or equal to 60, while the alternative hypothesis should state that the mean number is less than 60. Option B correctly states these hypotheses. Option A reverses the direction of the alternative hypothesis, while option C uses the sample mean instead of the population mean in the null hypothesis. Option D is not a valid set of hypotheses as it does not include the population mean of 60.
