How many tissues should a package of tissues contain? Researchers determined that 60 tissues is the mean number of tissues used during a cold. Suppose a random sample of 100 tissue users yielded the following data on the number of tissues used during a cold: X=52, S = 22. Suppose the test statistic does fall in the rejection region at a=0.05. Which of the following conclusion is correct? A. At a=0.05, there is sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues. OB. At a=0.05, there is insufficient evidence to conclude that the mean number of tissues used during a cold is not 60 tissues. OC. At a=0.05, there is not sufficient evidence to conclude that the mean number of tissues used during a cold is 60 tissues.
