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: = 52,S = 22. Suppose the test statistic does fall in the rejection region at α = 0.1. Which of the following conclusions is correct? Question 23 options: 1) At α = 0.1, there is sufficient evidence to conclude that the mean number of tissues used during a cold is not 60 tissues. 2) At α = 0.1, there is not sufficient evidence to conclude that the mean number of tissues used during a cold is 60 less than tissues. 3) At α = 0.1, there is insufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues. 4) At α = 0.1, there is sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues.
